TYPO3 Core

It can be argued that forcing users to remember their passwords leads to simple and easily guessable passwords.

Power users will use a password manager anyway. And for normal users, IMHO it's better to let them use their browsers autocomplete instead of "forcing" them to use everywhere 12345.

I would recommend to implement this feature. Nearly every external security company demands this feature in their pen tests now. It does not need to make sense in the end - they recommend this feature and we have to patch TYPO3 in order achieve it.
