If you've got a new phone or other mobile device, you can set it up for two-factor authentication (2FA). If you receive 2FA codes via email but you'd like to change to an authenticator app, see Changing your two-factor authentication method.
2FA is only affected if you change the device you want to use, not your phone number.
