Can you disable SMS on google? I've tried and have been unsuccessful. Phone is required to enable 2FA. Once that is enabled, I can add yubikeys. After adding yubikeys, I am unable to remove phone as a 2FA alternative.
- tptacek 10y agoYes: delete your phone number.
- pfg 10y agoIt's possible to disable SMS-based 2FA. Perhaps you need another backup option before you're allowed to remove the SMS option. In my case, I was able to do it with two U2F keys, TOTP and backup codes enabled. You might need to remove it as an account recovery number as well. Those can effectively downgrade your login to one factor.
- danjoc 10y ago>you need another backup option before you're allowed to remove the SMS option. This was the answer. Google prompt isn't allowed with hardware tokens. Backup codes evidently don't count. So the only way is to set up Google Authenticator on a phone. Authenticator from f-droid works. After I set up Authenticator, I no longer got the "Something went wrong. Try again" toast when trying to delete the sms number. Edit: Just realized what Yubico Authenticator is for :)
- niij 10y agoYou need a software token (Google Auth) or backup codes before removing the phone number.
- nickik 10y agoI was also unable to do this, but I tried earlier today and it worked. You have to have TOTP and Backup keys. Maybe this is a recent change.
