1). Use at least 8 characters, combination of lowercase and uppercase letters, numbers, and symbols in your password. Remember, the more the merrier.
2). Good and strong passwords are easy to remember but hard to guess. Iam:)2b23! — This has 10 characters and says "I am happy to be 23!".
3). Have fun with known short codes or sentences or phrases. 2B-or-Not_2b? — This one says "To be or not to be?"
