You don't need to enter your phone number to use Google's two factor. You can use their smartphone application to generate codes. If you don't want to do that, the algorithm is free and open-source so you can probably find an alternate implementation that works fine.
- crumblan 14y agoUnless I am mistaken, they won't let you do two-factor auth at all unless you put a phone number first.
- nollidge 14y agoI don't think they need a phone number if you use the Google Authenticator app on your phone. The pin for that is generated based on an initial random seed and the current date/time, not your cell number.
- fr0sty 14y agoThey do require it. If you remove it 2-factor-authentication is disabled. Nothing says that number needs to be your mobile (or one that you have regular access to) but you do need to provide one.
- SnowLprd 14y agoDoes that mean that you could use a Google Voice number? Presumably they already know that one, so "divulging" it shouldn't be an issue. ;^)
