What does HackerNews think of Authenticator?

Two-Factor Authentication Client for iOS

Language: Swift

#25 in iOS
#19 in Swift
hmm, Authenticator is open source (https://github.com/mattrubin/Authenticator). 2FA is also available in open source key manager program such as KeePass.

When it comes to 2FA, I would rather trust open source apps vs the ones made by Google/MS.

I use KeePassXC on a Linux desktop and store the 2FA codes in it. Every site that offers 2FA will let you use a code instead of scanning the QR image. As long as I have the underlying codes I can reuse them anywhere else.

In iOS I use 'Authenticator' - https://github.com/mattrubin/Authenticator. It's open source.
