@switchingsocial@mastodon.at What’s a good Google Authenticator alternative for iOS? andOTP is Android-only, FreeOTP seems to have been more or less abandoned and Authy isn't open-source AFAIK
@canteen @switchingsocial why not a Yubikey?
@HamDancer @canteen @switchingsocial Alas, as much as I love my Yubikey, not every sight I want to use 2FA with can work with it, yet.
@canteen @switchingsocial
I'm using Authenticator. It's MIT licensed.
@canteen @switchingsocial I use OTP Auth
@canteen @switchingsocial
The privacyIDEA authenticator (https://apps.apple.com/de/app/privacyidea-authenticator/id1445401301) is open source: https://github.com/privacyidea/privacyidea-authenticator-ios
It uses Google Cloud messaging for the Push-Token but TOTP/HOTP work fine. #2fa
@canteen @switchingsocial Tofu or OTP Auth are the ones I recommend. Tofu is fully open source and also recommended by PRISM Break.
