What's a good two-factor for iOS that's open source?
Discussion
I use bitwarden to store my 2fa codes. If you run vaultwarden yourself, you only need the client app to access it.
You need their Pro version for 2fa (or run your own instance) right? The guy this would be for probably wouldn't want to do either. I'm just trying to find one that doesn't do account backups and let's you keep track of your keys inside the app while preferably being a well used open source project. These might be high standards lol
While not 100% open source, I'm a big fan of YubiKey--if you're going to do 2FA, then there is no better solution IMHO.
Great product but for the person that will using it they just need to be able to keep track of master keys inside the app without backing anything up to the cloud. I doubt they'll spend even $5 for this use case.
