Password Security Check for TYPO3

What is it?

Since it is not possible out-of-the-box in TYPO3 to define password complexity rules of Backend and Frontend users, some users may choose very easy passwords for their user accounts. Especially for TYPO3 Backend Admin accounts, this can be dangerous, since it will be easier for attackers using brute force techniques to get access to the TYPO3 backend in this case.

This extension can help to get an overview or to get notified about TYPO3 Backend or Frontend users, who use a password that is found in a given list of popular passwords. The extension ships with a list of 10.000 most popular passwords used, but you can also use your own list (e.g. list with top passwords in local language).

Installation using Composer

The recommended way to install the extension is by using Composer. In your Composer based TYPO3 project root, just do composer require derhansen/pwd_security_check.

Installation as extension from TYPO3 Extension Repository (TER)

Download and install the extension with the TYPO3 extension manager module.


Please note, that the check can take a lot of time to finish. This depends primary on the amount of users and the amount of passwords to check.

Get Help: bin/typo3 help pwd_security_check:process

Command arguments:

  • mode Mode (0 = Backend Admin Users, 1 = Backend Users, 2 = Frontend Users)
  • recipients E-Mail addresses to receive notification separated by space.

Is this a hacker tool?

No, at least it is not meant to be one. Therefore matched passwords are not displayed. Also, it is not very worthwhile to use this tool and try to bruteforce crack a TYPO3 account password, as it does not support parallel checks and the task may take hours/days/weeks/years.
