Please be careful with your password selection, your password should be something you will remember, but that someone trying to break into your account would find hard to guess. You can use any combination of 6 to 20 upper and lower case letters, numbers, and punctuation. Please note that the password is case sensitive, so 'HELLO' is different from 'hello', which is different from 'hElLo'.
DO NOT USE YOUR NAME AS A PASSWORD! In fact, you should avoid using actual words at all. You might take two short words and combine them with a special character or number, as in 'robot4my', or 'eye-con'. You could also put together an acronym that is special to you, such as 'Notfsw' for 'None Of This Fancy Stuff Works.' Of course, these examples are now BAD passwords, since they are here.
