Ratings and reviews

Decent first attempt. Swipe to edit is fine. Swipe to delete is absurd. Should be a long press or something else less easy to trigger. Also, imports wind up with "No issuer" way too often; I'm not interested in going through and renaming half my entries. Finally, lack of support for custom or imported icons is not ideal. That being said, it's a perfectly serviceable 2fa app otherwise. It's just not on par with Aegis, which I'll continue using.

For its initial release, this app does rather well. After Authy unceremoniously DROPPED their desktop support, I've been looking for a replacement. This is it. Installed on W11, Android devices, and Ubuntu. Syncs between devices. There ARE a few glitches. ORDERING of the entries on ONE device forces the SAME ordering upon ALL devices, which is not necessarily desirable. Also, it would be helpful if the identifying ICONS were captured for all entries, as that helps in finding them. Bye-bye Authy.

For the most part, LOVE this app! Biggest win is displaying the next code before it is active. Biggest downsides, the swipe left and right swipe functionality. It would be great to be able to configure this. Another function that is missing is being able to change the icon for the Authenticator inside the app. For the most part, I do like the app, just a few little tweaks and it would be 5 stars.
