There are no password reset intervals, so you can change your password as little or as often as you want. However, you can keep strong passwords effective by changing them often. Here are some good password guidelines:
- Use at least eight characters (the more the better), but most people will find anything more than about 15 characters difficult to remember.
- Use a random mixture of characters, upper and lower case, numbers, punctuation, spaces and symbols.
- Don't use a word found in a dictionary, English or foreign.
Note: If you forget your password, you may be able to reset it. Learn how to reset your password.
