  • Works pretty well but has some bugs on iOS

    Works pretty well, but one of the more annoying bugs is if you have device sync on it “shuffles around” your codes whenever you open the app. If you have the desktop app and you organize your codes there, the phone will reflect it properly next time you close and reopen it.

  • Best authenticator

    I’ve used Proton services for a few years, and I just love how secure everything is, and how they continuously work to make great improvements. Thank you proton!!!

    Easy to set up and use, data can be exported, backed up, and it will show you the next code if the clock is running out on the current code. Very handy.

  • Very good

    This is a really nice Authenticator app, especially since it can sync with a desktop version in multiple ways. Not many Authenticators do that. The problem with this Authenticator is that it is too easy accidentally delete an account from your list with an accidental swipe. There is no need to for such a simple method of deletion on an Authenticator. It is not like you delete multiple items per day like email. The delete function should be very deliberate and have a confirmation step. Fix that and this would be about the best Authenticator currently available.

  • good job

    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.
