When making passwords for a character here are some things to think of:
Make sure passwords are a minimum of 12 characters.
Include upper case, lower case, and special characters (!,@,#,$,%,^,&,*,(,), -, +, =).
DO NOT have anything someone might know about you or your character in the password.
Make sure the password is easy for you to remember, but extremely difficult for others to guess.
