What are the security implications of using my google voice number as a backup phone number to my google account (the same account)? I've been doing this for a few years, and its been very convenient. Basically, any time I need to log in with a new browser or device, using the number for two factor SMS gives me codes on all other logged in gmail windows, and on my phone.

So there is a pretty significant risk of getting locked out entirely if your authentication tokens for your Google account expire on all devices at the same time. Yes, that's unlikely. But if it happens, we're screwed. A better option would probably be to set up two Google accounts with two Google Voice numbers and use them to cross-validate each other. I think I'll go do that now.
