Actually, please do NOT have a maxlength on your password field. Instead, if the contents are too long, disable the submit button and tell me my password is too long. Why? Because I never actually type in a password. I generate a long one and copy & paste it in. And when you put a max length on the field, I think my password is FooBarBazBatAwesome, and you think my password is FooBarBazBat.... and that is going to screw me. I've had this happen on more than one occasion. For God's sake, do not put a max length on your password field. It silently drops any characters that are too long without notifying the user that it's doing so.
