  • So far so good, and better than Google Authenticator

    Import was easy, and the UI and functionality are very good.

  • Best Auth

    This is the best App that used so far. But one adjustment could be made when opening in Macbook, it is so big, you could do it much smaller, resizing up to only 4 keys and scroll.

  • Looks nice but a couple of functional flaws

    Update: Now supports various sorting options. Nice. +1 star 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.

  • Fantastic

    Love the app! I migrated from Authy because I this has a much more modern sleek design, is more feature rich, and has a macOS client. Only thing that drives me a little crazy is that the app icon is so small compared to my other apps on my Home Screen. Keep up the good work. I hope this continues to improve.

  • Not great

    Works for all of your everyday 2FA needs. Missing quality of life features like being able to set icons for each entry or upload custom ones (given that half of my 50 entries are missing one)

  • Buggy

    On iOS the search often ends up stuck on the middle of my screen making only the top half scrollable!

  • Import issues
