In password security, the longer the better. With a password manager, using more than 24 characters is simple. Unless, of course, the secure password is not accepted due to its length. (In this case, through STOVE.)
Possibly indicating cleartext storage of a limited field (which is an absolute no-go), or suboptimal or lacking security practices.
I like the ones that just tell you your password strength.
Subtle shaming of bad passwords without giving bad actors hints as to what the minimum (and thus most likely) password is.
