What’s your prefer two-factor authentication app for iOS?
I'm looking for an app that offers the best combination of platform compatibility (preferably available on Mac OS, iPad OS, and iOS), security, usability, and reliability.
It would be great if the app is open source and has a backup feature as well.
I’ve been using the one in 1Password. The main downside is it’s annoying to add a otp into the app if you can’t scan the QR code. I did most of my websites with my iPad and my phone.
Using 1Password kinda defeats the purpose of 2FA though. If someone steals your one password, they can access all of your passwords and your authenticator.
I do have an app set up just for 1Password 2fa. Also, when you sign into a new device with 1Password you need:
The password
2fa code
Additional “Secret Key” that is account specific that you can only get by logging into 1Password from a trusted device and “adding new device”
At that point, if they get in, they either really want my info or I’m being held at gunpoint.
