I have relatively long Passwords, because why not, and had problems with pages restricting the number of characters you can enter in the login window, but not the registration window. Or restricting password length and cutting your password off, but not telling you about it, so you gotta figure out that they set the first 30 characters of the saved password as your password.
Always fun to deal with. I could make it a lot easier for me by just using shorter passwords, but I think deep down I'm a masochist.
Bitwarden inserts them automatically, and if I ever have to do it manually for some reason, it just doubles the fun. Hasn't happened to me yet, though.
