General Config Settings

Craft supports several configuration settings that give you control over its behavior.

To set a new config setting, open config/general.php and define it in one of the environment config arrays, depending on which environment(s) you want the setting to apply to.

For example, if you want to allow Craft to be updated in dev environments but not on staging or production environments, do this:




 





 














return [
    // Global settings
    '*' => [
        'allowUpdates' => false,
        // ...
    ],

    // Dev environment settings
    'dev' => [
        'allowUpdates' => true,
        // ...
    ],

    // Staging environment settings
    'staging' => [
        // ...
    ],

    // Production environment settings
    'production' => [
        // ...
    ],
];

Here’s the full list of config settings that Craft supports:

# System

# accessibilityDefaults

Allowed types
array (opens new window)
Default value
[ 'alwaysShowFocusRings' => false, 'useShapes' => false, 'underlineLinks' => false, ]
Defined by
GeneralConfig::$accessibilityDefaults (opens new window)
Since
3.6.4

The default user accessibility preferences that should be applied to users that haven’t saved their preferences yet.

The array can contain the following keys:

  • alwaysShowFocusRings - Whether focus rings should always be shown when an element has focus
  • useShapes – Whether shapes should be used to represent statuses
  • underlineLinks – Whether links should be underlined

# allowAdminChanges

Allowed types
boolean (opens new window)
Default value
true
Defined by
GeneralConfig::$allowAdminChanges (opens new window)
Since
3.1.0

Whether admins should be allowed to make administrative changes to the system.

When this is disabled, the Settings section will be hidden, the Craft edition and Craft/plugin versions will be locked, and the project config and Plugin Store will become read-only—though Craft and plugin licenses may still be purchased.

It’s best to disable this in production environments with a deployment workflow that runs composer install and propagates project config updates on deploy.

Don’t disable this setting until all environments have been updated to Craft 3.1.0 or later.

# allowSimilarTags

Whether users should be allowed to create similarly-named tags.

# allowUpdates

Whether Craft should allow system and plugin updates in the control panel, and plugin installation from the Plugin Store.

This setting will automatically be disabled if allowAdminChanges is disabled.

# autoLoginAfterAccountActivation

Whether users should automatically be logged in after activating their account or resetting their password.

# autosaveDrafts

Allowed types
boolean (opens new window)
Default value
true
Defined by
GeneralConfig::$autosaveDrafts (opens new window)
Since
3.5.6

Whether drafts should be saved automatically as they are edited.

Note that drafts will be autosaved while Live Preview is open, regardless of this setting.

# backupOnUpdate

Whether Craft should create a database backup before applying a new system update.

# cacheDuration

Allowed types
mixed
Default value
86400 (1 day)
Defined by
GeneralConfig::$cacheDuration (opens new window)

The default length of time Craft will store data, RSS feed, and template caches.

If set to 0, data and RSS feed caches will be stored indefinitely; template caches will be stored for one year.

See craft\helpers\ConfigHelper::durationInSeconds() (opens new window) for a list of supported value types.

# cpHeadTags

Allowed types
array (opens new window)
Default value
[]
Defined by
GeneralConfig::$cpHeadTags (opens new window)
Since
3.5.0

List of additional HTML tags that should be included in the <head> of control panel pages.

Each tag can be specified as an array of the tag name and its attributes.

For example, you can give the control panel a custom favicon (etc.) like this:

'cpHeadTags' => [
    // Traditional favicon
    ['link', ['rel' => 'icon', 'href' => '/icons/favicon.ico']],
    // Scalable favicon for browsers that support them
    ['link', ['rel' => 'icon', 'type' => 'image/svg+xml', 'sizes' => 'any', 'href' => '/icons/favicon.svg']],
    // Touch icon for mobile devices
    ['link', ['rel' => 'apple-touch-icon', 'sizes' => '180x180', 'href' => '/icons/touch-icon.svg']],
    // Pinned tab icon for Safari
    ['link', ['rel' => 'mask-icon', 'href' => '/icons/mask-icon.svg', 'color' => '#663399']],
],

# defaultCpLanguage

The default language the control panel should use for users who haven’t set a preferred language yet.

# defaultCpLocale

The default locale the control panel should use for date/number formatting, for users who haven’t set a preferred language or formatting locale.

If this is null, the defaultCpLanguage config setting will determine which locale is used for date/number formatting by default.

# defaultDirMode

Allowed types
mixed
Default value
0775
Defined by
GeneralConfig::$defaultDirMode (opens new window)

The default permission to be set for newly-generated directories.

If set to null, the permission will be determined by the current environment.

# defaultFileMode

The default permission to be set for newly-generated files.

If set to null, the permission will be determined by the current environment.

# defaultSearchTermOptions

The default options that should be applied to each search term.

Options include:

  • attribute – The attribute that the term should apply to (e.g. 'title'), if any. (null by default)
  • exact – Whether the term must be an exact match (only applies if attribute is set). (false by default)
  • exclude – Whether search results should exclude records with this term. (false by default)
  • subLeft – Whether to include keywords that contain the term, with additional characters before it. (false by default)
  • subRight – Whether to include keywords that contain the term, with additional characters after it. (true by default)

# defaultTemplateExtensions

Allowed types
string (opens new window)[]
Default value
[ 'html', 'twig', ]
Defined by
GeneralConfig::$defaultTemplateExtensions (opens new window)

The template file extensions Craft will look for when matching a template path to a file on the front end.

# defaultWeekStartDay

The default day new users should have set as their Week Start Day.

This should be set to one of the following integers:

  • 0 – Sunday
  • 1 – Monday
  • 2 – Tuesday
  • 3 – Wednesday
  • 4 – Thursday
  • 5 – Friday
  • 6 – Saturday

# devMode

Allowed types
boolean (opens new window)
Default value
false
Defined by
GeneralConfig::$devMode (opens new window)

Whether the system should run in Dev Mode (opens new window).

# disabledPlugins

Array of plugin handles that should be disabled, regardless of what the project config says.

'dev' => [
    'disabledPlugins' => ['webhooks'],
],

This can also be set to '*' to disable all plugins.

'dev' => [
    'disabledPlugins' => '*',
],

This should not be set on a per-environment basis, as it could result in plugin schema version mismatches between environments, which will prevent project config changes from getting applied.

# disallowRobots

Allowed types
boolean (opens new window)
Default value
false
Defined by
GeneralConfig::$disallowRobots (opens new window)
Since
3.5.10

Whether front end requests should respond with X-Robots-Tag: none HTTP headers, indicating that pages should not be indexed, and links on the page should not be followed, by web crawlers.

This should be set to true for development and staging environments.

# enableTemplateCaching

Whether to enable Craft’s template {% cache %} tag on a global basis.

# errorTemplatePrefix

The prefix that should be prepended to HTTP error status codes when determining the path to look for an error’s template.

If set to '_' your site’s 404 template would live at templates/_404.html, for example.

# extraAllowedFileExtensions

List of file extensions that will be merged into the allowedFileExtensions config setting.

# extraAppLocales

List of extra locale IDs that the application should support, and users should be able to select as their Preferred Language.

Only use this setting if your server has the Intl PHP extension, or if you’ve saved the corresponding locale data (opens new window) into your config/locales/ folder.

# handleCasing

Allowed types
string (opens new window)
Default value
GeneralConfig::CAMEL_CASE
Defined by
GeneralConfig::$handleCasing (opens new window)
Since
3.6.0

This can be set to one of the following:

  • camel – for camelCase
  • pascal – for PascalCase (aka UpperCamelCase)
  • snake – for snake_case

# headlessMode

Allowed types
boolean (opens new window)
Default value
false
Defined by
GeneralConfig::$headlessMode (opens new window)
Since
3.3.0

Whether the system should run in Headless Mode, which optimizes the system and control panel for headless CMS implementations.

When this is enabled, the following changes will take place:

  • Template settings for sections and category groups will be hidden.
  • Template route management will be hidden.
  • Front-end routing will skip checks for element and template requests.
  • Front-end responses will be JSON-formatted rather than HTML by default.
  • Twig will be configured to escape unsafe strings for JavaScript/JSON rather than HTML by default for front-end requests.
  • The loginPath, logoutPath, setPasswordPath, and verifyEmailPath settings will be ignored.

With Headless Mode enabled, users may only set passwords and verify email addresses via the control panel. Be sure to grant “Access the control panel” permission to all content editors and administrators. You’ll also need to set the baseCpUrl config setting if the control panel is located on a different domain than your front end.

# httpProxy

The proxy server that should be used for outgoing HTTP requests.

This can be set to a URL (http://localhost) or a URL plus a port (http://localhost:8125).

# indexTemplateFilenames

Allowed types
string (opens new window)[]
Default value
[ 'index', ]
Defined by
GeneralConfig::$indexTemplateFilenames (opens new window)

The template filenames Craft will look for within a directory to represent the directory’s “index” template when matching a template path to a file on the front end.

# ipHeaders

List of headers where proxies store the real client IP.

See yii\web\Request::$ipHeaders (opens new window) for more details.

If not set, the default craft\web\Request::$ipHeaders (opens new window) value will be used.

# isSystemLive

Whether the site is currently live. If set to true or false, it will take precedence over the System Status setting in Settings → General.

# limitAutoSlugsToAscii

Whether non-ASCII characters in auto-generated slugs should be converted to ASCII (i.e. ñ → n).

This only affects the JavaScript auto-generated slugs. Non-ASCII characters can still be used in slugs if entered manually.

# maxBackups

The number of backups Craft should make before it starts deleting the oldest backups. If set to false, Craft will not delete any backups.

# maxRevisions

The maximum number of revisions that should be stored for each element.

Set to 0 if you want to store an unlimited number of revisions.

# maxSlugIncrement

The highest number Craft will tack onto a slug in order to make it unique before giving up and throwing an error.

# permissionsPolicyHeader

The Permissions-Policy header that should be sent for web responses.

# phpMaxMemoryLimit

The maximum amount of memory Craft will try to reserve during memory-intensive operations such as zipping, unzipping and updating. Defaults to an empty string, which means it will use as much memory as it can.

See https://php.net/manual/en/faq.using.php#faq.using.shorthandbytes (opens new window) for a list of acceptable values.

# previewIframeResizerOptions

Custom iFrame Resizer options (opens new window) that should be used for preview iframes.

'previewIframeResizerOptions' => [
    'autoResize' => false,
],

# privateTemplateTrigger

The template path segment prefix that should be used to identify “private” templates, which are templates that are not directly accessible via a matching URL.

Set to an empty value to disable public template routing.

# runQueueAutomatically

Whether Craft should run pending queue jobs automatically when someone visits the control panel.

If disabled, an alternate queue worker must be set up separately, either as an always-running daemon (opens new window), or a cron job that runs the queue/run command every minute:

* * * * * /path/to/project/craft queue/run

This setting should be disabled for servers running Win32, or with Apache’s mod_deflate/mod_gzip installed, where PHP’s flush() (opens new window) method won’t work.

# sameSiteCookieValue

Allowed types
string (opens new window)
Default value
null
Defined by
GeneralConfig::$sameSiteCookieValue (opens new window)
Since
3.1.33

The SameSite (opens new window) value that should be set on Craft cookies, if any.

This can be set to 'None', 'Lax', 'Strict', or null.

This setting requires PHP 7.3 or later.

# sendContentLengthHeader

Allowed types
boolean (opens new window)
Default value
false
Defined by
GeneralConfig::$sendContentLengthHeader (opens new window)
Since
3.7.3

Whether a Content-Length header should be sent with responses.

# sendPoweredByHeader

Whether an X-Powered-By: Craft CMS header should be sent, helping services like BuiltWith (opens new window) and Wappalyzer (opens new window) identify that the site is running on Craft.

# slugWordSeparator

The character(s) that should be used to separate words in slugs.

# testToEmailAddress

Configures Craft to send all system emails to either a single email address or an array of email addresses for testing purposes.

By default, the recipient name(s) will be “Test Recipient”, but you can customize that by setting the value with the format ['me@domain.tld' => 'Name'].

# timezone

The timezone of the site. If set, it will take precedence over the Timezone setting in Settings → General.

This can be set to one of PHP’s supported timezones (opens new window).

# translationDebugOutput

Whether translated messages should be wrapped in special characters to help find any strings that are not being run through Craft::t() or the |translate filter.

# useEmailAsUsername

Whether Craft should set users’ usernames to their email addresses, rather than let them set their username separately.

If you enable this setting after user accounts already exist, run this terminal command to update existing usernames:

php craft utils/update-usernames

# useFileLocks

Whether to grab an exclusive lock on a file when writing to it by using the LOCK_EX flag.

Some file systems, such as NFS, do not support exclusive file locking.

If not set to true or false, Craft will try to detect if the underlying file system supports exclusive file locking and cache the results.

# useIframeResizer

Allowed types
boolean (opens new window)
Default value
false
Defined by
GeneralConfig::$useIframeResizer (opens new window)
Since
3.5.5

Whether iFrame Resizer options (opens new window) should be used for Live Preview.

Using iFrame Resizer makes it possible for Craft to retain the preview’s scroll position between page loads, for cross-origin web pages.

It works by setting the height of the iframe to match the height of the inner web page, and the iframe’s container will be scrolled rather than the iframe document itself. This can lead to some unexpected CSS issues, however, because the previewed viewport height will be taller than the visible portion of the iframe.

If you have a decoupled front end (opens new window), you will need to include iframeResizer.contentWindow.min.js (opens new window) on your page as well for this to work. You can conditionally include it for only Live Preview requests by checking if the requested URL contains a x-craft-live-preview query string parameter.

You can customize the behavior of iFrame Resizer via the previewIframeResizerOptions config setting.

# Environment

# aliases

Any custom Yii aliases (opens new window) that should be defined for every request.

# backupCommand

The shell command that Craft should execute to create a database backup.

When set to null (default), Craft will run mysqldump or pg_dump, provided that those libraries are in the $PATH variable for the system user running the web server.

You may provide your own command, which can include several tokens Craft will substitute at runtime:

  • {file} - the target backup file path
  • {port} - the current database port
  • {server} - the current database hostname
  • {user} - user that was used to connect to the database
  • {password} - password for the specified {user}
  • {database} - the current database name
  • {schema} - the current database schema (if any)

This can also be set to false to disable database backups completely.

# defaultCookieDomain

The domain that cookies generated by Craft should be created for. If blank, it will be left up to the browser to determine which domain to use (almost always the current). If you want the cookies to work for all subdomains, for example, you could set this to '.my-project.tld'.

# resourceBasePath

Allowed types
string (opens new window)
Default value
'@webroot/cpresources'
Defined by
GeneralConfig::$resourceBasePath (opens new window)

The path to the root directory that should store published control panel resources.

# resourceBaseUrl

Allowed types
string (opens new window)
Default value
'@web/cpresources'
Defined by
GeneralConfig::$resourceBaseUrl (opens new window)

The URL to the root directory that should store published control panel resources.

# restoreCommand

The shell command Craft should execute to restore a database backup.

By default Craft will run mysql or psql, provided those libraries are in the $PATH variable for the user the web server is running as.

There are several tokens you can use that Craft will swap out at runtime:

  • {path} - the backup file path
  • {port} - the current database port
  • {server} - the current database hostname
  • {user} - the user to connect to the database
  • {database} - the current database name
  • {schema} - the current database schema (if any)

This can also be set to false to disable database restores completely.

# Routing

# actionTrigger

Allowed types
string (opens new window)
Default value
'actions'
Defined by
GeneralConfig::$actionTrigger (opens new window)

The URI segment Craft should look for when determining if the current request should be routed to a controller action.

# activateAccountSuccessPath

Allowed types
mixed
Default value
''
Defined by
GeneralConfig::$activateAccountSuccessPath (opens new window)

The URI that users without access to the control panel should be redirected to after activating their account.

See craft\helpers\ConfigHelper::localizedValue() (opens new window) for a list of supported value types.

# addTrailingSlashesToUrls

Whether auto-generated URLs should have trailing slashes.

# allowUppercaseInSlug

Whether uppercase letters should be allowed in slugs.

# baseCpUrl

The base URL Craft should use when generating control panel URLs.

It will be determined automatically if left blank.

The base control panel URL should not include the control panel trigger word (e.g. /admin).

# cpTrigger

The URI segment Craft should look for when determining if the current request should route to the control panel rather than the front-end website.

This can be set to null if you have a dedicated hostname for the control panel (e.g. cms.my-project.tld), or you are running Craft in Headless Mode. If you do that, you will need to ensure that the control panel is being served from its own web root directory on your server, with an index.php file that defines the CRAFT_CP PHP constant.

define('CRAFT_CP', true);

Alternatively, you can set the baseCpUrl config setting, but then you will run the risk of losing access to portions of your control panel due to URI conflicts with actual folders/files in your main web root.

(For example, if you have an assets/ folder, that would conflict with the /assets page in the control panel.)

# invalidUserTokenPath

Allowed types
mixed
Default value
''
Defined by
GeneralConfig::$invalidUserTokenPath (opens new window)

The URI Craft should redirect to when user token validation fails. A token is used on things like setting and resetting user account passwords. Note that this only affects front-end site requests.

See craft\helpers\ConfigHelper::localizedValue() (opens new window) for a list of supported value types.

# loginPath

Allowed types
mixed
Default value
'login'
Defined by
GeneralConfig::$loginPath (opens new window)

The URI Craft should use for user login on the front end.

This can be set to false to disable front-end login.

Note that this config setting is ignored when headlessMode is enabled.

See craft\helpers\ConfigHelper::localizedValue() (opens new window) for a list of supported value types.

# logoutPath

Allowed types
mixed
Default value
'logout'
Defined by
GeneralConfig::$logoutPath (opens new window)

The URI Craft should use for user logout on the front end.

This can be set to false to disable front-end logout.

Note that this config setting is ignored when headlessMode is enabled.

See craft\helpers\ConfigHelper::localizedValue() (opens new window) for a list of supported value types.

# omitScriptNameInUrls

Whether generated URLs should omit index.php (e.g. http://my-project.tld/path instead of http://my-project.tld/index.php/path)

This can only be possible if your server is configured to redirect would-be 404s to index.php, for example, with the redirect found in the .htaccess file that came with Craft:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.+) /index.php?p= [QSA,L]

Even when this is set to true, the script name could still be included in some action URLs. If you want to ensure that index.php is fully omitted from all generated URLs, set the pathParam config setting to null.

# pageTrigger

The string preceding a number which Craft will look for when determining if the current request is for a particular page in a paginated list of pages.

Example Value Example URI
p /news/p5
page /news/page5
page/ /news/page/5
?page /news?page=5

If you want to set this to ?p (e.g. /news?p=5), you’ll also need to change your pathParam setting which defaults to p. If your server is running Apache, you’ll need to update the redirect code in your .htaccess file to match your new pathParam value.

# pathParam

The query string param that Craft will check when determining the request’s path.

This can be set to null if your web server is capable of directing traffic to index.php without a query string param. If you’re using Apache, that means you’ll need to change the RewriteRule line in your .htaccess file to:

RewriteRule (.+) index.php [QSA,L]

# postCpLoginRedirect

Allowed types
mixed
Default value
'dashboard'
Defined by
GeneralConfig::$postCpLoginRedirect (opens new window)

The path users should be redirected to after logging into the control panel.

This setting will also come into effect if a user visits the control panel’s login page (/admin/login) or the control panel’s root URL (/admin) when they are already logged in.

See craft\helpers\ConfigHelper::localizedValue() (opens new window) for a list of supported value types.

# postLoginRedirect

Allowed types
mixed
Default value
''
Defined by
GeneralConfig::$postLoginRedirect (opens new window)

The path users should be redirected to after logging in from the front-end site.

This setting will also come into effect if the user visits the login page (as specified by the loginPath config setting) when they are already logged in.

See craft\helpers\ConfigHelper::localizedValue() (opens new window) for a list of supported value types.

# postLogoutRedirect

Allowed types
mixed
Default value
''
Defined by
GeneralConfig::$postLogoutRedirect (opens new window)

Allowed types
mixed
Default value
'setpassword'
Defined by
GeneralConfig::$setPasswordPath (opens new window)

The URI or URL that Craft should use for Set Password forms on the front end.

Note that this config setting is ignored when headlessMode is enabled, unless it’s set to an absolute URL.

You might also want to set invalidUserTokenPath in case a user clicks on an expired password reset link.

# setPasswordRequestPath

Allowed types
mixed
Default value
null
Defined by
GeneralConfig::$setPasswordRequestPath (opens new window)
Since
3.5.14

The URI to the page where users can request to change their password.

See craft\helpers\ConfigHelper::localizedValue() (opens new window) for a list of supported value types.

If this is set, Craft will redirect .well-known/change-password requests (opens new window) to this URI.

You’ll also need to set setPasswordPath, which determines the URI and template path for the Set Password form where the user resets their password after following the link in the Password Reset email.

# setPasswordSuccessPath

Allowed types
mixed
Default value
''
Defined by
GeneralConfig::$setPasswordSuccessPath (opens new window)

The URI Craft should redirect users to after setting their password from the front end.

See craft\helpers\ConfigHelper::localizedValue() (opens new window) for a list of supported value types.

string (opens new window)
Default value
'siteToken'
Defined by
GeneralConfig::$siteToken (opens new window)
Since
3.5.0

'token'
Defined by
GeneralConfig::$tokenParam (opens new window)

The query string parameter name that Craft tokens should be set to.

# usePathInfo

Whether Craft should specify the path using PATH_INFO or as a query string parameter when generating URLs.

Note that this setting only takes effect if omitScriptNameInUrls is set to false.

# useSslOnTokenizedUrls

Determines what protocol/schema Craft will use when generating tokenized URLs. If set to 'auto', Craft will check the current site’s base URL and the protocol of the current request and if either of them are HTTPS will use https in the tokenized URL. If not, will use http.

If set to false, Craft will always use http. If set to true, then, Craft will always use https.

# verifyEmailPath

Allowed types
mixed
Default value
'verifyemail'
Defined by
GeneralConfig::$verifyEmailPath (opens new window)
Since
3.4.0

The URI or URL that Craft should use for email verification links on the front end.

Note that this config setting is ignored when headlessMode is enabled, unless it’s set to an absolute URL.

See craft\helpers\ConfigHelper::localizedValue() (opens new window) for a list of supported value types.

# verifyEmailSuccessPath

Allowed types
mixed
Default value
''
Defined by
GeneralConfig::$verifyEmailSuccessPath (opens new window)
Since
3.1.20

The URI that users without access to the control panel should be redirected to after verifying a new email address.

See craft\helpers\ConfigHelper::localizedValue() (opens new window) for a list of supported value types.

Default value
'CraftSessionId'
Defined by
GeneralConfig::$phpSessionName (opens new window)

The name of the PHP session cookie.

# rememberUsernameDuration

Allowed types
mixed
Default value
31536000 (1 year)
Defined by
GeneralConfig::$rememberUsernameDuration (opens new window)

The amount of time Craft will remember a username and pre-populate it on the control panel’s Login page.

Set to 0 to disable this feature altogether.

See craft\helpers\ConfigHelper::durationInSeconds() (opens new window) for a list of supported value types.

# rememberedUserSessionDuration

Allowed types
mixed
Default value
1209600 (14 days)
Defined by
GeneralConfig::$rememberedUserSessionDuration (opens new window)

The amount of time a user stays logged if “Remember Me” is checked on the login page.

Set to 0 to disable the “Remember Me” feature altogether.

See craft\helpers\ConfigHelper::durationInSeconds() (opens new window) for a list of supported value types.

# requireMatchingUserAgentForSession

Whether Craft should require a matching user agent string when restoring a user session from a cookie.

# requireUserAgentAndIpForSession

Whether Craft should require the existence of a user agent string and IP address when creating a new user session.

# userSessionDuration

Allowed types
mixed
Default value
3600 (1 hour)
Defined by
GeneralConfig::$userSessionDuration (opens new window)

The amount of time before a user will get logged out due to inactivity.

Set to 0 if you want users to stay logged in as long as their browser is open rather than a predetermined amount of time.

See craft\helpers\ConfigHelper::durationInSeconds() (opens new window) for a list of supported value types.

# Security

# blowfishHashCost

The higher the cost value, the longer it takes to generate a password hash and to verify against it.

Therefore, higher cost slows down a brute-force attack.

For best protection against brute force attacks, set it to the highest value that is tolerable on production servers.

The time taken to compute the hash doubles for every increment by one for this value.

For example, if the hash takes 1 second to compute when the value is 14 then the compute time varies as 2^(value - 14) seconds.

# cooldownDuration

Allowed types
mixed
Default value
300 (5 minutes)
Defined by
GeneralConfig::$cooldownDuration (opens new window)

The amount of time a user must wait before re-attempting to log in after their account is locked due to too many failed login attempts.

Set to 0 to keep the account locked indefinitely, requiring an admin to manually unlock the account.

See craft\helpers\ConfigHelper::durationInSeconds() (opens new window) for a list of supported value types.

# csrfTokenName

Allowed types

86400 (1 day)
Defined by
GeneralConfig::$defaultTokenDuration (opens new window)

The default amount of time tokens can be used before expiring.

See craft\helpers\ConfigHelper::durationInSeconds() (opens new window) for a list of supported value types.

# deferPublicRegistrationPassword

By default, Craft requires a front-end “password” field for public user registrations. Setting this to true removes that requirement for the initial registration form.

If you have email verification enabled, new users will set their password once they’ve followed the verification link in the email. If you don’t, the only way they can set their password is to go through your “forgot password” workflow.

# elevatedSessionDuration

Allowed types
mixed
Default value
300 (5 minutes)
Defined by
GeneralConfig::$elevatedSessionDuration (opens new window)

The amount of time a user’s elevated session will last, which is required for some sensitive actions (e.g. user group/permission assignment).

Set to 0 to disable elevated session support.

See craft\helpers\ConfigHelper::durationInSeconds() (opens new window) for a list of supported value types.

# enableBasicHttpAuth

Allowed types
boolean (opens new window)

Since
3.5.0

Whether front-end web requests should support basic HTTP authentication.

# enableCsrfCookie

Whether to use a cookie to persist the CSRF token if enableCsrfProtection is enabled. If false, the CSRF token will be stored in session under the csrfTokenName config setting name. Note that while storing CSRF tokens in session increases security, it requires starting a session for every page that a CSRF token is needed, which may degrade site performance.

# enableCsrfProtection

Whether to enable CSRF protection via hidden form inputs for all forms submitted via Craft.

# invalidLoginWindowDuration

Allowed types
mixed
Default value
3600 (1 hour)
Defined by

See craft\helpers\ConfigHelper::durationInSeconds() (opens new window) for a list of supported value types.

# maxInvalidLogins

The number of invalid login attempts Craft will allow within the specified duration before the account gets locked.

# preventUserEnumeration

When true, Craft will always return a successful response in the “forgot password” flow, making it difficult to enumerate users.

When set to false and you go through the “forgot password” flow from the control panel login page, you’ll get distinct messages indicating whether the username/email exists and whether an email was sent with further instructions. This can be helpful for the user attempting to log in but allow for username/email enumeration based on the response.
