Can I change my verification method if I fail the authentication step using the method I first selected?
No, if you have failed to verify your identity using any method, you will not be able to start again using a different method for the same transaction. Your card will be blocked after three unsuccessful attempts with any method and you will need to contact Customer Services on 0800 008 008* or +44 1604 269452* from outside the UK (24/7).
