A. Mix letters and numbers, more than six characters, and force changes yearly

B. Mix letter and numbers, no less than four characters, and less than nine characters

C. Use all uppercase letters, force changes quarterly, and write the passwords down

D. Keep a written list, use easy to remember names, and don't force password use

E. Mix letters and numbers, force changes every three months, and require password lengths of six to eight characters
