Change password for frontend users

What does it do?

This TYPO3 extension contains a plugin to allow logged in frontend users to change their password. The new user password is validated against the TYPO3 password policy for frontend users.

Password changes for frontend users can be enforced and passwords can expire after a certain amount of days.

Features:

• Change password plugin
• Validates the password against the TYPO3 password policies for frontend users
• Force password change for frontend users
• Redirect to configured page when password change is required
• Password expiration after a configurable amount of days
• Optional require the current password in order to change the password
• Optional require a change password code, which is sent to the users email address, in order to change the password

Screenshot

The screenshot below shows the output of the "Change Frontend User Password" plugin after the user tried to submit a weak password.

Installation

1. Install the extension from the TYPO3 Extension Repository or using composer and add the Static Typoscript "Change password for frontend users" to your TypoScript template.

2. Add the site set "Change password for frontend users" to your site

3. Create a new page and make sure, that the page is only visible to logged in frontend users.

4. Add the Plugin "Change Frontend User Password" to the page created in step 2

5. Change Site settings to your needs. Please note, that if you want to use the password change enforcement, you must set fe_change_pwd.changePasswordPid to the page uid of the page created in step 2

6. Change TypoScript settings to your needs.

7. Optionally change the path to the extension templates in TypoScript and modify the templates to your needs.

New fe_user fields

The extension adds two new fields to the fe_users table (see screenshot)

If the checkbox "User must change password at next login" is set and a valid changePasswordPid is configured, the user will be redirected to the configured page after login when accessing pages as configured in the plugin.tx_fechangepwd.settings.redirect section.

The password expiry date defines the date, after a user must change the password.

Tip: If you quickly want all frontend users to change their passwords, you can use a simple SQL statement to set the field in the database like shown in this example UPDATE fe_users set must_change_password=1;

Site configuration settings

• fe_change_pwd.changePasswordPid (integer) The pid to redirect to if a password change is required. This is usually the page with the Plugin of the extension

• fe_change_pwd.redirect.allAccessProtectedPages (bool) If set to 1, a redirect to the configured fe_change_pwd.changePasswordPid will be forced for all access protected pages. Note, that if this option is set, the includePageUids is ignored!

• fe_change_pwd.redirect.includePageUids (string) A redirect to the configured changePasswordPid will be forced for the configured PIDs separated by a comma

• fe_change_pwd.redirect.includePageUidsRecursionLevel (integer) The recursion level for all pages configured in fe_change_pwd.redirect.includePageUids. Use this option, if you e.g. want to force a redirect for a page and all subpages

• fe_change_pwd.redirect.excludePageUids (string) No redirect will be forced for the configured PIDs separated by a comma

• fe_change_pwd.redirect.excludePageUidsRecursionLevel (integer) The recursion level for all pages configured in fe_change_pwd.redirect.excludePageUids. Use this option, if you e.g. want to exclude a page and all subpages for the redirect

TypoScript configuration settings

The following TypoScript settings are available.

plugin.tx_fechangepwd.settings.requireCurrentPassword

• enabled (bool) If set to 1, the user must enter the current password in order to set a new password. Default setting is 1.

plugin.tx_fechangepwd.settings.requireChangePasswordCode

• enabled (bool) If set to 1, the user must enter a change password code, which will be sent to the users email address, in order to set a new password. Default setting is 0.
• validityInMinutes (integer) The time in minutes the change password code is valid, when it has been requested by the user.
• senderEmail (string) Sender email address for email send to user
• senderName (string) Sender name for email sent to user

plugin.tx_fechangepwd.settings.passwordExpiration

• enabled (bool) Is set to 1, new passwords will expire after the configured amount of days
• validityInDays (integer) The amount of days, a new password is valid before it needs to be changed

plugin.tx_fechangepwd.settings.afterPasswordChangeAction

• redirect (string) Redirects the user to the "update" action and adds a flash message, that the password has been updated.
• view (string) Shows the view for the update action with a message, that the password has been updated

Styling

The extension output is completely unstyled. Feel free to override the fluid templates to your needs.

Overriding Fluid email templates

If the email template used for the "change password code" email need to be overridden, this can be changed in $GLOBALS['TYPO3_CONF_VARS']['MAIL']['templateRootPaths'][750] or by adding e template override for the ChangePasswordCode template.

Possible Errors

No password hashing service

The extension will not save a users password, if it can not be hashed. If this scenario occurs, the following exception is shown:

No secure password hashing service could be initialized. Please check your TYPO3 system configuration

Possible CSRF detected

When the extension detects a possible CSRF, the following message is shown:

Possible CSRF detected. Ensure a valid "changeHmac" is provided.

If you unexpectedly see this message, ensure you add the changeHmac property as described in "Breaking Changes" for version 1.5.0

For developers

PSR-14 events

The extension currently contains the following PSR-14 events:

• Derhansen\FeChangePwd\Controller\PasswordController
  • AfterPasswordUpdatedEvent
  • ModifyUpdatePasswordResponseEvent
• Derhansen\FeChangePwd\Middleware\ForcePasswordChangeRedirect
  • ModifyRedirectUrlParameterEvent

Additionally, the extension also dispatches the TYPO3 core PSR-14 event TYPO3\CMS\Core\PasswordPolicy\Event\EnrichPasswordValidationContextDataEvent

If additional user data has to be considered for password validation, please use this event to add the data to the ContextData DTO.

Versions

Breaking changes

Version 5.0.0

This version contains major breaking changes, which must be migrated manually. The following TypoScript settings must be migrated to site settings:

• plugin.tx_fechangepwd.settings.changePasswordPid => fe_change_pwd.changePasswordPid
• plugin.tx_fechangepwd.settings.redirect.* => fe_change_pwd.redirect.*

This change is required, since full TypoScript is not available for cached pages in a PSR-15 MiddleWare.

This breaking change limits the plugin to be used once per Site, if the "Must change password" or "Password expiry date" features are used, which both need to redirect to a single page UID, which now is configured in site settings.

Version 4.0.0

This version contains major breaking changes, since now the TYPO3 password policy is used for password validation.

• All password validators have been removed in favor to TYPO3 password policies. Make sure to check, if the TYPO3 default password policy suits your needs
• The pwned password check has been removed. If this check is required, please use TYPO3 extension add_pwd_policy in the password policy for frontend users
• The extension now requires the current user password by default. This check can be disabled in settings using requireCurrentPassword
• The extension requires TYPO3 security.usePasswordPolicyForFrontendUsers feature toggle to be active
• Dropped TYPO3 11.5 compatibility.

Version 3.0.0

• Dropped TYPO3 9.5 and 10.4 compatibility.
• Changed file extension für TypoScript files to .typoscript
• Replaced signal slot with PSR-14 event

Version 2.0.0

Dropped TYPO3 8.7 compatibility.

Version 1.5.0

Added CSRF protection.

If you use an own template for "Edit.html", you must add the following code inside <f:form>...</f:form>.

<f:form.hidden property="changeHmac" />

Prior to version 1.5.0, the extension did contain a CSRF vulnerability, if settings.requireCurrentPassword was disabled (default). In order to mitigate the issue, the property changeHmac has been added to the DTO. This property contains a HMAC, which is unique for the current logged-in user. When the provided changeHmac does not match the expected value, an exception is thrown when the form is submitted.
