How many times can I attempt to enter the authentication code before my account is blocked?

You have a total of three consecutive attempts to enter your authentication code correctly across your transaction history.

If you fail to authenticate yourself twice on any transactions, you will only have one attempt remaining for your next transaction. If you fail an authentication attempt three consecutive times, your account will be blocked from making any further online transactions. You’ll need to contact Customer Services 0800 008 008* or +44 1604 269452* from outside the UK (24/7) to unblock it. You can still use your card for contactless and Chip and PIN transactions and to log in to online servicing.
