If you’ve lost access to your phone
If you’ve lost access to your phone number or you’ve changed it, you can use your back-up method (another UK phone number or authenticator app) if you’ve added one.
If you do not have a back-up method, check if you can change how you get security codes:
Sign in to your GOV.UK One Login.
Enter your password.
When asked to enter the security code, select Problems with the code.
Select Check if you can change how you get security codes.
You’ll only be able to change how you get security codes if you’ve already proved your identity with GOV.UK One Login.
If you’re told you cannot change how you get security codes, contact GOV.UK One Login.
If you’re told you can change how you get security codes, you’ll need to prove your identity using the GOV.UK ID Check app. This is because we need to know it’s you and helps to keep your GOV.UK One Login safe.
We’ll ask some questions to make sure you can use the GOV.UK ID Check app. Then we’ll tell you how to download and use the app to prove your identity.
You can then choose how you want to get security codes. You can get codes by text message to your UK mobile phone number or from an authenticator app.
Changing how you get security codes will remove your previous default and back-up method, if you’ve set one up.
