The system doesn't pick and choose - the password must have been incorrect - perhaps a spelling mistake or capitals somewhere.
You can tick "remember me" when you log in which will mean you stay logged in and don't need to type your password each time.
Not exactly a normal first post, but it looks like you've sorted it out. I'm sure you'll find plenty of information here that will make the rigamarole all worthwhile.
