One of my work applications doesn't allow you to use any of the letters in the same spot or any repeating letters . And it expires every 45 days . So for example if I used Batman1 for my password . I can't just switch to Captain2 because the second letter is the same . And you can't use something like Poophead because there are 2 O's in a row . It's a nightmare every time it expires .

When it expires, bump every character up by one - A/a becomes B/b, 1 becomes 2, for symbols use the next one on the row.

That also means they are saving that information. I doubt a single character can be usefully hashed. Seems like a security nightmare.

It's also some shitty program that is all black screen with green text that was probably made in the 90s . From what I understand it's used by a bunch of different shipping companies and very unintuitive to use .

Edit: just googled it and it was released in 1988 it's called As400

Ah, crap.

Those are some aggressive password rule options.

On the plus side, it may be over engineered all of the way to fuck and back. (Or not)

Edit: I searched for "as400 password rules" and that was the first hit.
