Ok, serious question: how do you manage your tokens? What happens if your device flies out of the window?
A couple of months ago I managed to break the screen of my tablet with 20-30 services I use 2FA (Google Authenticator). I had to spend about 50 bucks just to get a new screen and repair it.
For some of these services I had the token saved on my keepass, but I always felt a little dirty doing that. If there was a way to keep backups of Google Authenticator data, I'd take it in a heartbeat.
