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 came across a recent Wirecutter article from The New York Timesthat recommends Cisco DUO Mobile as the top choice, followed by Authy and Google Authenticator.

I would greatly appreciate your insights and security perspectives.

Thank you!

    If you also use a password manager, then 1Password is what I use since it handles both and does cross platform and can auto fill on mobile.

      Any solution that holds both together… is not really a 2fa solution imo.

        True but still better than no 2FA. Would be great if these password managers informed a second level of security (ie different password) into their 2FA.

    Surprisingly, Microsoft Authenticator works very well. On iOS it lets you back up your authentication tokens to iCloud and on Android I believe there is some way to do this too (I don’t have an Android phone so idk). I would avoid Google Authenticator because to the best of my knowledge there is no way to back up, and at some point in the past it crashed on me and I lost all my 2FA logins, which was a huge pain to recover from.

      Authenticator allows you to back up your passcodes to to your google account. I actually prefer DUO’s way of backing up 2FA codes by protecting them with a different password. I don’t like google’s approach as it basically means that if your google account is compromised then the attackers have the keys to the castle.

    There’s 2FAS. It’s open source, available on Android and iOS as well as on desktop through the browser extension.

      The only gripe I have about this is that third party browsers on MacOS don’t support Passkey. If you use Safari it’s absolutely wonderful, but…safari.

      Still though, it isn’t incredibly difficult to just go into Settings to get passwords, but it’s still a pain.

    I use a yubico hardware key, for all of my TOT0 and bitwarding password manager and my Google Voice for the 2FA

    I have been a big fan of authy for a few years. Works well for me.

    I use OTP Auth. Syncs via iCloud and has an Apple Watch app. Plus allows export which is convenient for if I ever want to switch platforms back to Android.

    I just use a keepass vault and KeePassium (Strongbox is also great) after deciding I don’t trust Authy.

    Biggest advantage over Authy for me is that I control the data and that the solution is open source.

    Vault is synced locally with syncthing but a vault on a cloud drive requiring a key file that is local is also a good option.

    Backups are easy. KeePassXC can be used on the desktop for totp.

    Vault is not kept with my password vault.

    If you wear an Apple Watch DUO has a watch app and so I’ve migrated all my accounts that support duo to it so I can leave my phone in my pocket and just look at my wrist
