Choosing a Password
It's important that you choose a good password and keep it private. Doing so prevents other people from using your account to post false messages under your name or perform other illegal activities.
A good password:
- is between 6 and 8 characters in length.
- contains letters and numbers
- is easily remembered so you don’t have to write it down.
- contains both upper case and lower case letters.
A bad password:
- is easily guessed (your mother’s name, birthday, etc).
- is less than 6 characters long.
- matches your account information, like your login name.
- is a dictionary word, proper name, or non-random characters (eg. aaaaaa).
Guidelines/Suggestions:
- Some passwords are case sensitive, such as your email password. If you use a password with upper and lowercase characters, you must type those characters exactly.
- Combine parts or words, letters and numbers, but note that special characters are not permitted
