3D Secure is a tool to help you make online payments safely. When you make certain high-value transactions online, you’ll receive a push notification from Starling, allowing you to approve this payment directly in the Starling app. 

For certain merchants, or if you can’t receive this push notification, you need to enter a secure unique password, which you can find in the “Card” screen of the Starling app. All you have to do is enter that password to confirm that it's really you, and we'll process the sale.

Please note that, during the month of July 2020, you may still receive a secure unique password by SMS to approve your 3D Secure transactions, as we make the transition to this new in-app authentication process.
