What’s an authentication card?

It’s a new way to help you confirm your identity when accessing Barclaycard online servicing. You’ll need the authentication card to confirm it’s really you whenever you log in, giving you an extra layer of security. It has a zero credit limit and is used for verification step only. You won’t be able to make any payments with it.

If you have a transactional card and you also service your account online, you won’t receive a separate authentication card. You will just use your Barclaycard Commercial card to log in to online serving.
