Here's another one: Don't do what some banks do when they separate the password field into multiple boxes for various characters in your password. It's enough of a hassle trying to remember the password sometimes, let alone when you've got to randomly work out what the 3rd, 7th, 10th and 15th characters of it are too. They also do this for the pin number too, which is obviously much easier to figure out but again adds unneeded stress for little extra security.
