How to backup 2FA (lemm.ee)

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?

Aegis is a free open source TOTP 2FA app like Google Authenticator, and available on both F-Droid and Google Play. You should be able to export from Google Authenticator and import into Aegis.

Edit: I had assumed because Aegis had an option to import from Google Authenticator that this would mean you could export in bulk. Bad assumption to make, it sounds like you can do it if you have a rooted phone but Authenticator doesn’t make it easy. I did find this that shows a method to do a handful at once: https://blog.jay2k1.com/2021/11/17/how-to-bulk-migrate-from-google-authenticator-to-aegis/

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

Huh. I was not able to make it work, perhaps I just overlooked something.
