Passwords should be:
- At least 8 characters in length.
- Include a random mixture of letters (uppercase and lowercase), numbers and symbols characters (e.g . ! @ # $ % ^ & * ( ) – + ? ).
- Choose a password that is easy to remember
(see Tips for choose secure and easy to remember passwords below).
- Change your passwords frequently.
Passwords should not:
- Be based on personal information. e.g. name, nickname, birthday, relatives’ names, etc.
- Use your login name in any form. This includes backwards, doubled, capitalised, etc.
- Contain words in the dictionary. This includes foreign language words, slang, jargon and proper names.
- Comprise characters that are easily spotted when typing. Sequential keys on the keyboard, like: qwerty, mnbvcx or 123456 and so on are easy for people looking over your shoulder to recognise.
- Be re-used. If someone already knows your old password, re-using the password will open the door for them.
- Contain common misspelling and substitution (e.g. replacing “e” with “3” or “i” with “1”)
