I had the same problem and didn't want to keep all of my eggs in the same basket, plus I lost faith in these backup apps after Google Auth lost user codes at some point.

I decided to create a private backup which I control and so I built a client-side web app that encrypts QR codes (like 2FA codes). It was inspired by a similar CLI based project I saw here on HN. I still use Authy (for now) but now I have encrypted images that I can decrypt and rescan easily. And since they're just images I saved them in various places and even printed out copies should I lose my phone or Authy access.

To 'migrate' my codes out of Authy I just went through each site and regenerated the codes (plus encrypted them). It's annoying that they force you to do this but doesn't take too long.

I'm still polishing it up but it works well and I would love some feedback if there's anyone who finds it useful - https://encrypt-qr-codes.netlify.app/
