This is relative to the public web dir. DefaultStorage will be created with that configuration. Do not access manually but via `\TYPO3\CMS\Core\Resource\ResourceFactory::getDefaultStorage().` ## lockRootPath {#typo3confvars-be-lockrootpath} This option has been extended to support an array of root path prefixes to allow for multiple storages to be listed (a string was expected before).It is suggested to use the new array-based syntax, which will be applied automatically once this setting is updated via Install Tool configuration wizard. Migration:// Before $GLOBALS['TYPO3_CONF_VARS']['BE']['lockRootPath'] = '/var/extra-storage'; // After $GLOBALS['TYPO3_CONF_VARS']['BE']['lockRootPath'] = [ '/var/extra-storage1/', '/var/extra-storage2/', ];See also the security bulletin "Path Traversal in TYPO3 File Abstraction Layer Storages". - **$GLOBALS\['TYPO3_CONF_VARS'\]\['BE'\]\['lockRootPath'\]** - *type:* array of file paths - *Default:* `[]` These absolute paths are used to evaluate, if paths outside of the project path should be allowed.

On error an error header is sent and the script exits. Works like IP masking for users configurable through TSconfig. See syntax for that (or look up syntax for the function `\TYPO3\CMS\Core\Utility\GeneralUtility::cmpIP())` Have also a look into the [security guidelines](https://docs.typo3.org/permalink/t3coreapi:security-global-typo3-options-ipmasklist@11.5). ## lockSSL {#typo3confvars-be-lockssl} - **$GLOBALS\['TYPO3_CONF_VARS'\]\['BE'\]\['lockSSL'\]** - *type:* bool - *Default:* false If set, the backend can only be operated from an SSL-encrypted connection (https). A redirect to the SSL version of a URL will happen when a user tries to access non-https admin-urls Have also a look into the [security guidelines](https://docs.typo3.org/permalink/t3coreapi:security-global-typo3-options-lockssl@11.5). ## lockSSLPort {#typo3confvars-be-locksslport} - **$GLOBALS\['TYPO3_CONF_VARS'\]\['BE'\]\['lockSSLPort'\]** - *type:* int - *Default:* Use a non-standard HTTPS port for lockSSL.

The only possible value has been 'normal'. This behaviour stays unchanged.

Requires - zlib in your PHP installation and - special rewrite rules for .css.gzip and .js.gzip (please see `_.htacces` for an example). Range 1-9, where 1 is least compression and 9 is greatest compression. true as value will set the compression based on the PHP default settings (usually 5).

Default value is stored in class constant `\TYPO3\CMS\Core\Resource\Security\FileNameValidator::FILE_DENY_PATTERN_DEFAULT`. Have also a look into the [security guidelines](https://docs.typo3.org/permalink/t3coreapi:security-global-typo3-options-filedenypattern@11.5). ## interfaces {#typo3confvars-be-interfaces} - **interfaces** - *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['BE'\] - *type:* text - *Default:* backend This determines which interface options are available in the login prompt (All options: "backend,frontend") ## explicitADmode {#typo3confvars-be-explicitadmode} - **explicitADmode** - *Path:* $GLOBALS\['TYPO3_CONF_VARS'\]\['BE'\] - *type:* dropdown - *Default:* 'explicitAllow' - *allowedValues:* - **explicitAllow:** Administrators have to explicitly grant access for all editors and groups - **explicitDeny:** Editors have access to all content types by default, access has to explicitly restricted Sets the general allow/deny mode for Content Element Types (CTypes) when granting or restricting access for backend users ## flexformForceCDATA {#typo3confvars-be-flexformforcecdata} - **$GLOBALS\['TYPO3_CONF_VARS'\]\['BE'\]\[flexformForceCDATA'\]** - *type:* bool - *Default:* If set, will add CDATA to Flexform XML. Some versions of libxml have a bug that causes HTML entities to be stripped from any XML content and this setting will avoid the bug by adding CDATA. ## versionNumberInFilename {#typo3confvars-be-versionnumberinfilename} - **$GLOBALS\['TYPO3_CONF_VARS'\]\['BE'\]\['versionNumberInFilename'\]** - *type:* bool - *Default:* false - **If enabled, included CSS and JS files loaded in the TYPO3 Backend will** have the timestamp embedded in the filename, ie. `filename.1269312081.js` . This will make browsers and proxies reload the files if they change (thus avoiding caching issues). **IMPORTANT:** This feature requires extra `.htaccess` rules to work (please refer to the `typo3/sysext/install/Resources/Private/FolderStructureTemplateFiles/root-htaccess` file shipped with TYPO3). If disabled the last modification date of the file will be appended as a query-string. ## debug {#typo3confvars-be-debug} - **$GLOBALS\['TYPO3_CONF_VARS'\]\['BE'\]\['debug'\]** - *type:* bool - *Default:* false If enabled, the login refresh is disabled and pageRenderer is set to debug mode. Furthermore the fieldname is appended to the label of fields. Use this to debug the backend only! ## toolbarItems {#typo3confvars-be-toolbaritems} - **toolbarItems** - *type:* array - *Default:* \[\] Registered toolbar items classes > [!NOTE] > This configuration variable will be removed with version 12.0. Extensions who want to > support both LTS 11 and 12 can set this variable and depend on Services to load the > toolbar in LTS 12. Using this configuration variable is **not deprecated** in > LTS 11. ## HTTP {#typo3confvars-be-http} - **$GLOBALS\['TYPO3_CONF_VARS'\]\['BE'\]\['HTTP'\]** - *type:* array - *Default:* ```php [ 'Response' => [ 'Headers' => ['clickJackingProtection' => 'X-Frame-Options: SAMEORIGIN'] ] ] ``` Set HTTP headers to be sent with each backend request. Other keys than `['Response']['Headers']` are ignored. ## passwordHashing {#typo3confvars-be-passwordhashing-classname} ### className {#classname} - **$GLOBALS\['TYPO3_CONF_VARS'\]\['BE'\]\['passwordHashing'\]\['className'\]** - *type:* string - *Default:* `\TYPO3\CMS\Core\Crypto\PasswordHashing\Argon2iPasswordHash::class` - *allowedValues:* - **`\TYPO3\CMS\Core\Crypto\PasswordHashing\Argon2iPasswordHash::class`** Good password hash mechanism. Used by default if available. - **`\TYPO3\CMS\Core\Crypto\PasswordHashing\Argon2idPasswordHash::class`** Good password hash mechanism. - **`\TYPO3\CMS\Core\Crypto\PasswordHashing\BcryptPasswordHash::class`** Good password hash mechanism. - **`\TYPO3\CMS\Core\Crypto\PasswordHashing\Pbkdf2PasswordHash::class`** Fallback hash mechanism if argon and bcrypt are not available. - **`\TYPO3\CMS\Core\Crypto\PasswordHashing\PhpassPasswordHash::class`** Fallback hash mechanism if none of the above are available. ### options {#typo3confvars-be-passwordhashing-options} - **$GLOBALS\['TYPO3_CONF_VARS'\]\['BE'\]\['passwordHashing'\]\['options'\]** - *type:* array - *Default:* \[\] Special settings for specific hashes. See [Available hash algorithms](https://docs.typo3.org/permalink/t3coreapi:password-hashing-available-algorithms@11.5) for the different options depending on the algorithm.
