Due to the adoption of the new 3D Secure 2.0 (also known as 3DS2) security standard amongst card providers, you’re now required to authorise your online payments. This is to reduce the risk of fraud and prevent the use of your credit or debit card without your authorisation.
When making a payment using your credit or debit card online, you may now be asked to authorise it by your card provider. The authentication method varies between card providers, but this could be a code sent to your mobile phone, which you need to enter to complete your payment, or a prompt on your mobile banking app.
