Horrible pain to set up Please learn from Microsoft  their app and web tie in is seamless  super simple to set up and use. Anytime I need to validate sign in a phone notification would pop up and all I need to do hit approve or deny signin. At a minimum provide some a note in where to go in the website to activate the authenticator app. I was starting to feel sketchy that this could be a spoofed google app to steal your info... After scanning and entering the long code manually  it still says wrong code in verification.
