Hi @damon52, you will receive a message on screen advising your computer is unrecognised from time to time and this is due to the cookies being cleared from your web browser; this is how we recognise a customer’s device. Normally when this message pops up you should be able to continue your log in by requesting a One Time Access Code to your mobile phone or landline. What would prevent you from completing this process would be part of your security being locked.


Please send a private message to @Tesco-Bank  with your full name, DOB and postcode and I'll be able to help you reset your security details - Caroline

I am trying to change my e mail address and my mobile number on my credit card account, I log in but because I need a code, I can’t get as wrong mobile number to text the code too, so I can’t get any further

@Swebby8444 Sorry to hear you've had this trouble. I'm afraid I'd need to ask that you give us a call to update your number. If you give our Online Helpdesk a call on 0345 300 3511 (24/7), they'll be able to do this for you. I'm sorry for the inconvenience.

I recently changed email address however, whilst acknowledgement went to this, my monthly rate update email went to my old email.

Can you please explain why this happened as my online account only contains my new one?

@bazzabears1960 Thanks for getting in touch. When a change is to be made, we collate contact details ahead of time. If you update your details after we’ve planned our mailing schedule, it would go to the previous email address. As long as you received the confirmation, all further correspondence will be sent to the correct email address. I'm sorry for any confusion this has caused.

I am living in Australia and I have been locked out of my Credit Card online account as they password they had sent out to me expiredby  the time the letter was sent to my address. I have since moved house and my card expires in Sept. I need to update my details to stop the new card being sent to the wrong address. I have tried calling the helpdesk but got one of my security questions wrong. How do I get out of this situation. I can write a letter and have my future corrspondence sent to my UK address.


Any help is appreciated.
