When I want to add 2FA with the Google authenticator, Google always want to add 2FA with Phone verification instead.

I Googled it and all articles are mentioning the same URL, which asks for a phone number instead of generating an authenticator key.

What do it need to do, to activate the authenticator verification instead of phone/SMS verification?


1 Answer 1


Even to activate the Authenticator, first you need to complete SMS/Voice setup.

Then, follow the directions for your type of device explained on Google Help page for 2-Step Verification.

    Meh. I wanted the authenticator app, to avoid giving google my phone number. The app is such a nice idea for 2FA without giving out too many personal details ...

  • Could I add someone's phone number, set up TOTP 2FA, then remove the phone number?
