So basically what title says.
Im using 2FA with google authenticator for multiple accounts. What if my phone gets stolen? Can I have some kind of backup? Or maybe sync with some self hosted service?
Bonus question: what 2FA should I use instead of google?
I uses https://authy.com/
Separat from my passwords
Just a heads up. There is no way to export from authy. So if you ever want to switch apps for whatever reason, lets say they were bought by big evil corp., then you would have to go and regenerate all your keys. Where as a good app would let you export and import from anywhere
