An extension to specify secure password rules and force backend users to change their passwords, if the password is older then a defined limit.

In extension settings you can define:

  • Minimum number of capital characters
  • Minimum number of lowercase characters
  • Minimum number of digits
  • Minimum number of special characters
  • Minimum length of password
  • Maximum days before password must change

If a backend user logs in and his password needs to change, user will be logged out and redirected to comfortable password change form. After password was changed, the user will automatically logged in and can start his work in backend.

The password rules will also be checked when the user tries to change his password in user settings in backend.

Users imported from extension ig_ldap_sso_auth will be ignored.


This extension isn't compatible with typo3/cms-rsaauth, because typo3/cms-rsaauth will replace the given passwords through RSA hashes by an AJAX request before the password change form will be submitted. Therefore, RSA hashes aren't equal, so the "passwords do not match"-Validator doesn't work anymore. BUT you don't need typo3/cms-rsaauth if you already have HTTPS enabled, because it does exactly the same thing.

Furthermore, you have to set the loginSecurityLevel to the default value normal and not rsa.

Install and usage

  1. Basic install via composer

    composer req "move-elevator/me-backend-security":"^2.0"
  2. Modify extension settings in TYPO3 backend

  3. Be safer :)
