Also, if anyone is interested in alternative authentication you can try Authy app instead of google authenticator because Authy is connected to your phone number, not the device itself, so if you lose your phone there's no problem if you still retain the same phone number. unlike google authenticator, losing your phone can be a nightmare if you didn't record all the proper data. You should still record all data while using Authy, but it is much less of a problem to retrieve it.
