Maximum Password length for login?
When I just tried to create an account I tried using a 100 character password (because I can - I use LastPass).
The login gave me a misleading error message telling me three was something else that was wrong, not that my password was too long.
When I changed it to a 50 character password it accepted my password.
I'm guessing not many people try 100 character long passwords, and arguably 50 character passwords are quite strong, the error message should correctly state that the error was that it was too long.
The web page should also clearly state what the maximum length is in case people use password managers such as the excellent LastPass.
And while you are at it, take a good look at LastPass.
