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’ve had a case in the past where I reduced my password to the limit, but after account creation, I was not able to log in.
Turns out they had an off-by-one issue, and a password with a length slightly below the limit worked fine.
I once got locked out of an HP printer because it chopped off the last few characters of a password. Only figured it out because somebody had made a comment online about password length
Experienced a site some years ago that let me I put however long password I wanted (my default is 52 in my password manager), but turns out it only used the first 20 or so.
