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.
My favorite is when they don’t have this check, but silently slice the string to meet the requirement, so that you can’t login with the original password the next time.
My bank used to do that back in the early 2000’s, I moved banks.
Metro Bank did something like this to me.
Wells Fargo used to do this. They cut my 16 character password to 8 and negated capitalization. Which is why I don’t use them anymore
amazon also had it a couple years ago
