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 use Authy and am logged in on multiple devices so if I lose my phone I can still access the 2FA on my laptop. Then log back into the new phone using the laptop.
