Passwords

The same username and password are used to access both Windows and Linux. The account is only authorised for your use and you may now allow anyone else to use your account. Doing so is in breach of School policy and disciplinary action will be taken against anyone infringing this rule.

Anyone who has a valid reason for using the computing facilities will be allocated their own account and must not use that of another. Unauthorised use of accounts is against school policy, and may be classed as a criminal offence.

Users must change their initial passwords. Failure to do so within seven days will result in automatic account closure. Passwords must be at least 8 characters in length and must not be a dictionary word (in any language) or names, places, etc. You are advised to include numbers, mixed case and/or non-alphanumeric characters. Your password must not be made up of numbers only and should not be your ID number or contain your username.

The following complextity requirements are placed on passwords:

  • The password must be at least eight characters long
  • The password must contain characters from at least three of the following catergories:
    • English uppercase characters (A-Z)
    • English lowercase characters (a-z)
    • Numbers 0 - 9
    • Non-alphanumeric (e.g. !, $, #, %)
  • The password does not contain a substring of the user's username of three or more characters in length.

You must change your password at least once every six months and you may not use any of the last 10 passwords. When changing you password, the previous 10 passwords may be stored to ensure compliance with this requirement.

Passwords should be:

  • Easy for you to remember
  • Difficult for others to guess

One way of getting a strong but memorable password is to use a phrase and take the first letter of each word to make up the password, for example:

My password is hard for people to guess!

would become the password:

Mpih4ptg!

The password is made harder to guess by swapping the word "for" with the number "4".

Under no circumstances tell anyone your password.

Anyone means Everyone!
