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?
If there is a way, I was unable to find it
Yes, I just did it. Go to google auth - transfer accounts - you get QR code, screenshot it - and import in Aegis
