Why are some of the options to authenticate myself greyed out?

This happens when we don’t have relevant contact details registered to your account. Please make sure we have your latest mobile phone number and email address, so we can give you more options to authenticate online. You can update these details by calling us on 0800 008 008*, +44 1604 269452* from outside the UK (24/7) or contacting your Barclaycard Relationship Manager. Barclaycard Business card customers can also update their details by logging into their online servicing account.
