I was wandering through
https://www.cryptopp.com/wiki/Special:PasswordPolicies , which comes
from Mediawiki 1.38.2.
The first line for Autoconfirmed Users says:
Password must be at least 1 character long
(MinimalPasswordLength) (suggest change on login)
I think there are several problems with the page in general and text
in particular. First, a 1 character password is not really acceptable
in practice. It is probably time to increase the size of a minimum
password, to something like 16.
Second, the referenced variable, MinimalPasswordLength, is deprecated.
Or $wgMinimalPasswordLength is deprecated.

It might be a good idea for someone to visit the documentation for
Special:PasswordPolicies and maybe update it.
