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!!!

I wanted to try another free MFA app. Been using Aegis for a long time. Though I have no complaints with Aegis but it seemed pretty barebones. 2FAS blends both style and open source security. You can group tokens based on work or personal use. Logos let you identify token easily for a service from the list. Also, offers encrypted backup over Google drive which is frankly a convenience when switching devices. Aegis involved manually exporting and then importing backups if you change phones.
