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 got a login on an IBM system. I logged in and moved to the change password mask. Changed my password to something filling out the 12 character new password field. Logged out, and got the login mask again. With an eight character password field.
