Ratings and reviews

I seriously can't recommend this app enough. Great backup options and browser extensions that are easy to pair with the android app. Encrypted backups and easily shared between devices. Clean gui and simple to use. To top it off it's open source, I've used many other apps before but this ticks all the boxes. Love the fact the code are not kept in the browser and you have to approve them on your phone. And then it autofills for you. Thanks to the developers for creating an amazing product.

So far, so good. A simple UI, a good sync option, optional dark mode, active search, and hidden tokens. I've tried the backup/sync between my phone and tablet for 1 account and will gradually be migrating everything from Authy, as I've had enough of them killing a good thing. For a 5* rating, I'd love to see tiles as an option as well as the current lists, landscape view to match when my tablet is in landscape mode, and a timer when tokens are hidden.

Best authenticator app I've ever used and will stick with. The devs are great at the work they do, providing this at no cost to users (donations are accepted which they deserve) and hope they will continue to. Very happy with the app, simple, straight forward and secures your numerous logins that hackers would otherwise love to compromise. Thank you devs, keep up the great work! 👍
