How do I change the phone number I use to sign in?
To change the phone number where you get your security code, go to https://www.login.gov/ and select “Manage Account” to sign into your login.gov account. Once signed in, select “edit” next to the phone number. Enter the phone number and select “confirm change.” login.gov will immediately send your security code to confirm the new phone number.
If you cannot receive the security code because you no longer have access to your phone, you will need to sign in using your personal key.
