Longer passwords are stronger and more effective in protecting your account. Try for at least 15 characters. Other strategies for creating strong passwords include these:
- Mix upper- and lowercase letters, rAndoMly.
- Replace 1 or 2 letters with numeric digits.
- Use a passphrase.
Your password is like your toothbrush: change it periodically, and never share it. See the ITS Safe Computing page for more information.
