Hello,

Currently the password validators in Django will happily accept
`aaaaaaaaaaaa` ('a' * 12) as a password. I believe that adding a password
validator that checks for repeated patterns would vastly improve password
complexity. The implementation of such a validator is very simple:

{{{
import re

repeat_matcher = re.compile(r'(.+?)\1+')
match = repeat_matcher.match(password)
repeat_cnt = len(match.group(0)) // len(match.group(1)) - 1 if match else
0
}}}
`repeat_cnt` for `alaalaala` should be 2.

Hi Michel,

As you are suggesting a new feature for Django, you first need to propose
and discuss the idea with the community and gain consensus. To do that,
please consider starting a new conversation on the
[https://forum.djangoproject.com/c/internals/5 Django Forum], where you'll
reach a broader audience and receive additional feedback.

I'll close the ticket for now, but if the community agrees with the
proposal, please return to this ticket and reference the forum discussion
so we can re-open it. For more information, please refer to
[https://docs.djangoproject.com/en/stable/internals/contributing/bugs-and-
features/#requesting-features the documented guidelines for requesting
features].
