A strong password must be complex, so that it cannot be easily guessed. Ideally, a strong password should make use of upper and lower case letters, digits and special characters (&, @, # etc.)and should not be based on a dictionary word or a proper name. Passwords should be at least eight characters long and should be changed regularly.
A strong password is your first line of defence against security and privacy threats. You need strong passwords in the following areas:
- Local access to standalone computers
- Network access
- Access to Websites holding sensitive data, such as personal or financial details
- Access to valuable or confidential data
