Why do I need a one time passcode?

For extra security, we may ask you for a one time passcode to make sure it’s you logging into Online Banking. A One Time Passcode is specific to the current transaction and it is valid for 8 minutes from the time that it is sent to you.

One Time Passcode via mobile device

If we have your mobile details, you’ll get a one time passcode to your device within 1-2 minutes.

I don't have my mobile/mobile number invalid
