What is Strong Customer Authentication?

When shopping online with your Nationwide debit or credit card, there will sometimes be an extra step where we ask you to authenticate yourself. This means letting us know it’s definitely you making the online payment.

We give a range of ways to confirm your identity and let us know it’s really you, quickly and securely.


Why do we use Strong Customer Authentication?

It's all part of a regulation to help fight fraud and increase the security of your online payments. And it’s there to keep your money safe.

You can read more about how we protect you when you bank with us through our Digital Banking Promise.


Options for authenticating yourself

Banking app

When you checkout, we’ll send a secure message to your Banking app. You can use this to authenticate using fingerprint or facial recognition. Or you can simply tap in your passnumber.

What do I need to do next?

Using our secure Banking app is the easiest way to quickly confirm your online purchases if you have a compatible smartphone or tablet.

Download our Banking app (if you haven't already).

One-time passcodes: text message or landline

These unique codes can be used at checkout to confirm it’s really you making the online payment. They can be sent to you by text message or landline, using the contact details you have given us. You may experience this already when shopping online.

What do I need to do next?

Please make sure we have the correct mobile number, email address and landline for you as well as any additional card holders on your account. This is so you’ll get any authentication codes we send to you quickly and won’t get interrupted while shopping online.

Card reader

If you’re a debit card holder, you can authenticate online shopping transactions using the card reader you use for online banking. This option may be suitable if you don’t have a mobile phone or struggle to receive a mobile signal.

What do I need to do next?

Make sure you have a card reader.

If you’ve registered for the Internet Bank and have lost or never received a card reader, it’s easy to order a card reader.
