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.
Hey at least it told you there maximum length, i signed up paramount+ last night and it only said 42 characters was too long.
Maybe they allow more characters during the day /s
