Password Restrictions New passwords are subject to a variety of restrictions designed to prevent accounts from being compromised or, if they are compromised, to limit the time they remain so. Passwords must be between 8 and 32 characters long. Passwords must meet minimum criteria for difficulty to guess. Passwords cannot be re-used. Passwords A good password is easy for its owner to remember and difficult for anyone else to guess.
Good passwords are combinations of letters, numbers, and special characters.
Mixed-case passwords are more difficult to guess than passwords that are entirely uppercase or entirely lowercase. One strategy for creating acceptable passwords is to join two words together, or, better, to join two separate words with a special character. You can increase the security of passwords by replacing letters with numbers or special characters. Another strategy is to join together the first letters of a phrase or sentence. Avoid passwords like names, telephone numbers, birth dates and Social Security Numbers.
