Protecting your accounts

Simple steps to ensure your bank accounts stay secure.

Passwords and PINs
  • Memorise your PIN.
  • Choose a password that is a mix of letters and numbers.
  • Change your online banking password on a regular basis.
  • Never write your PIN down or share it with anyone (no matter how much you trust them).
  • Avoid making your PIN or password something easy to guess such as your date of birth or child’s name.
  • Useful tip

    When choosing a password, using a letter or number from a phrase or line from a song such as 2bORx2B makes your password easy to remember but difficult for other people to guess.

  • Install anti-virus and anti-spyware software on your computer and keep it up-to date.
  • Avoid installing pirated software. It’s a common way of tricking you into installing malicious software onto your computer.
  • Useful tip

    Updating your software is one of the easiest ways to keep your computer secure. Don’t ignore those notifications. Try setting up automatic software updates if you're likely to forget.

Phones and mobile devices
  • Keep your phone updated so you're using the latest operating software.
  • Use your phone data (not public Wi-Fi) when using online and mobile banking apps.
  • Install Apple's Find my iPhone or Google’s device manager for Android. If your phone is lost or stolen, you’ll be able to locate it and you can wipe the data remotely.
  • Lock your mobile device when you're not using it.
  • Only install apps from official stores, such as Apple's App Store or Android's Google Play and check the terms and conditions before you download an app.
  • Review your privacy permissions for each app so you know what apps have access to your information. You can do this under the 'Privacy' or 'Apps Permissions' menus in your phone's settings.
  • Avoid removing hardware restrictions (called rooting on Android and jailbreaking on Apple) on your mobile device. This weakens the in-built security protection.
  • Useful tip

    If your mobile phone is lost or stolen call us on 133 282. We can help you secure your mobile banking and disable any SMS security codes.

Online shopping
  • When making a payment or shopping online make sure the website address starts with “https://” which indicates a secure online shopping environment.
  • Useful tip

    Look for a padlock symbol in the bottom right-hand corner of the screen.

Email and social media
  • Never open links to webpages you don't recognise or don't seem quite right. It could be a malicious website designed to install malware on your device when you visit the link.
  • In a similar vein, never click on a link that doesn't look right or is sent to you by someone you don't know. Scammers often build fake websites designed to trick people into handing over their personal information.
  • Useful tip

    We will never contact you asking to confirm your PIN or passwords.
