My Favorite Authenticator

This is the best authenticator I have ever used. Simple with no bloat! Absolutely amazing!

great app, massive issue

this would be undoubtedly the best authenticator app on ios if not for one thing. this app is missing a supported way to export your keys. your totp keys are not viewable, they are not even saved to your icloud storage. this sucks. if you lose your phone, the app is deleted, your phone is wiped, or anything like that, your 2fa codes are gone. this sucks. this app doesn't seem to be maintained. i cant recommend tofu, but i've yet to find another 2fa totp app that is as good and simple as this one. very unfortunate. if the developer is reading this, you know what to do.

Dead Development

Seems to be dead. Last update on the appstore was a few years ago. The original dev passed the app onto his friend who has made changes to the backend app but not anything since June 1st, 2024. This is an amazing 2FA app, very minimalistic but it is missing a ton of QOL features.
