Ratings and reviews

Thank you so much for your brilliant app. This is the best Authenticator App I've ever tried. But just some small things that I wish I could change: 1. Smaller UI, so that more accounts could be shown. 2. Only the needed code is gonna be shown by tapping instead of showing everything in the dashboard. It's gonna be the ultimately perfect Authenticator.

This app is amazing! It's super smooth, open-source, with a very good UI/UX and awesome features. Switched from Authy. Aegis vs. 2fas? both are great, but I like 2fas more for its cloud backup and more. Love the next token preview. It also shows secrets and has export/import options. Thanks a lot for creating this! My only concern now is why 2fas has such long privacy policy page? Hope you'll make it shorter and simple like Aegis. Thanks!!!

As close to perfection as a 2FA app can be. The only thing I'd like to be able to do is add your own icon to a service if none is available. They provide options of how to get an icon added to the app, but both involve convincing someone else to do it. This way would be simpler and quicker.
