Ratings and Reviews
Good start, needs some polish
It’s a functional 2FA app. Backing up your iCloud and syncing between devices is nice. But the UI isn’t particularly smooth; it jitters when scrolling. Also, there’s no way to pin favorites or change ordering, so the ones I use the most I can’t move to the top.
I’m always a fan of Proton’s products, but I think I’ll be sticking with Bitwarden Authenticator for the time being.

Works at it should
I decided to wait a little while for some of the early bugs to be found and resolved before I installed.
But it was quite straightforward, adding my accounts as needed. iCloud sync worked a charm on multiple devices. And I also like that you can choose between multiple hash protocols. This, plus Protons’ reputation gives me more confidence in having my TOTP seeds on a less intrusive platform.
There are some quality of life updates that can be implemented. But it’s a promising start. Still early days.
Looks nice but a couple of functional flaws
The interface looks decent; import worked well; synching is working; BUT import created a few duplicates (not present in the source data); therefore there is no duplicate detection: and the display is ordered by time created, apparently—no way to sort by account or provider name, which would seem to be a most basic feature. Finally, there is no Export function: what’s labeled “Export” in setting is just a Proton-specific backup file, quite insecure. Room for improvement.
