My bank has a character limit, but they don’t tell you about it; they just trim the password you’ve set before hashing + saving it, then when you go to login if you don’t trim your password the same way they did, login fails.
I only know this because the mobile app will actually grey out the login button as soon as you enter more than the character limit. The web app just leaves you to be confused.
I had a similar situation with my health insurance company, except I think they added the character limit a while after I had set my password T_T. So, it worked for months, then they changed the mobile app so I couldn’t enter a long password… And then eventually they changed the website too and then I couldn’t log in at all. Thaaaaanks.
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.

What an absolutely shitty design.

Isn’t this also what Windows NT used to do? I feel like I remember encountering this scenario
