Doesnt lemmy also do it? I think I ve heard from Ruben at Boostforlemmy that lemmy only treats first 60 characters of your password as a password and the rest gets discarded. [citation needed]
The official web UI doesn't let you enter more than 60 characters, but doesn't indicate that at all. So you can keep typing past 60 characters but it won't get added to the input field and you can't really see that. If you paste a password into the field, it gets trimmed to 60 characters.
When creating a password, the server checks that it isn't longer than 60 characters and returns an error if so. On login, however, it silently trims the password to 72 bytes, because that's what the hashing algorithm they use supports.
Can't say I've ever tried to use a password quite that long, so I'm not sure.
Not ideal, but trimming it (especially when you're keeping 60 chars) isn't the end of the world. It was just super confusing that the web app doesn't trim it during login as well. There's no indication that your password was modified or what you've entered to login is too long. Just 'incorrect user/pass' despite entering what you've just set. That char limit for my bank is only 16 chars, so it's easy to hit.
It's a big deal IMO, particularly because at login it doesn't do the same. From the user perspective, your password has effectively been modified without your knowledge and no reasonable way of finding out. Good luck getting access to your account.
When a bank does this it should be considered gross negligence.
