Use strong passwords securely

Using a strong password makes it harder for fraudsters to gain access to your online accounts. A weak password can be cracked in less than five minutes. Make sure you know the recipe for creating strong passwords and how to keep them safe.


  • Create a strong password
    Make it long, usually at least 10-12 characters.
  • Choose one that is easy for you to remember but difficult for someone to guess (avoid obvious words like ‘password’, birthdays, pet names etc.).
  • Use a sentence or three random words mixed up with upper and lowercase letters, numbers and symbols spread throughout.
  • Keep passwords secure
    Avoid using the same password across multiple online accounts. If your information was stolen, the fraudster may then try your password on other accounts.
  • Never share your usernames or passwords.
  • Never allow web browsers (e.g. Google Chrome, Internet Explorer) to remember your passwords as you may be putting your information at risk.
  • Use finger print detection and an alphanumeric PIN with more than 4 digits where possible for mobile devices.
  • Activate two factor authentication (where available).
  • Consider using a ‘password manager’. It frees you from having to remember multiple complex passwords as you only need to remember the master password.
