How do I change or swap the Barclays account or phone number I used when registering for the Barclays app?

If you’d like to change any of the details you registered for the Barclays app, you’ll have to de-register from the app, reset it and then re-register with the new details.

Open the app, choose the side menu and select ‘Settings’. Then select 'Cancel my registration' and follow the instructions. Once you’ve reset the app, you’ll need to re-register by following the on-screen instructions.
