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.
the security team found out that only 93 Authy users out of 75 million were affected
Also this was a social engineering attack and if you’re syncing your 2fa seeds then you should be encrypting them with a secret. Cracking that should take years if not more.
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.
They released a Chrome and Edge extension to support 3rd party browsers about a year ago. I have never tried it but I noted it lets you be cross platform with the password feature.
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
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 am all-in on Bitwarden - and I use Apple's 2FA with a widget shortcut to Passwords in settings to unlock Bitwarden. For maximum security it makes sense to keep your OTP in a separate app, but if you choose to keep them in Bitwarden, it will add your 2FA codes to your clipboard after inserting your login and password on the site. Extremely convenient.
Bitwarden is light, multi-platform, will support Passkeys, open source, offers username and password generation, free (and VERY cheap if you want to unlock sharing). In my opinion nothing comes close.
