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?
Use Aegis lol.
There are many forms of 2FA. I’m guessing you mean TOTPs oh you actually wrote that, my bad lol.
I copy the keys from Aegis to KeePassXC. KeyPassXC’s database is part of my regular backup. This way I have two apps generating the same TOTPs.
Use Aegis on android or 2FAS on iOS. And just backup your seed on hdd/usb stick. Dont upload on cloud.
