FreeOTP Authenticator – Adds a second layer of security for your online accounts

[App] FreeOTP Authenticator

FreeOTP AuthenticatorFreeOTP Authenticator adds a second layer of security for your online accounts.

This works by generating one-time passwords on your mobile devices which can be used in conjunction with your normal password to make your login nearly impossible to hack. These passwords can be generated even when your phone is in airplane mode.

FreeOTP works with many of the great online services you already use, including Google, Facebook, Evernote, GitHub and many more! FreeOTP also may work for your private corporate security if they implement the standardized TOTP or HOTP protocols. This includes great enterprise solutions like FreeIPA.

FreeOTP is open source and free software! Licensed under the Apache 2.0 license, you can obtain the source code for FreeOTP at for review or modification. Contributions are welcome!

FreeOTP Authenticator user reviews :

This is simply the default 2-factor authenticator app to get. It is straightforward and easy to use, and perhaps most importantly is one of few (if not the only serious one?) that doesn’t either have ads, or require login on various cloud services just to get to your secure tokens.

small, functional, no ads. I’ve added Google, Microsoft, CloudFlare and Humble Bundle accounts. I keep using it, but I can’t add stream account (it’s quite special case), neither look or exports secret keys to transfer the 2FA data to my other phone. Also, app can’t use a site’s favicon, and doesn’t even have dark background mode. +1 star for letting it be FOSS.

Safe and simple and easy UI, not relying on SMS (which is unsafe, and country-dependant), works for all countries. And it’s open source. No need for export (there are password managers to keep the main code for you). Thanks for deveping this

I like the app, though there is a couple of issues images: 1. when I add 6th image the 1st one disappears, it seems like there is a limit on amount of images 2. after application restart all images disappear Phone: xiaomi mi a2 lite, android 8. Could you please check it out and fix if possible.

Great while it lasted! It appears development has ceased, and it is recommended to migrate to andOTP. Thank you for this app

Keep all your tokens in one place! No need to hunt for Code Generators among countless menus nor rely on insecure SMS for two factor authentication. Will read the QR codes that other apps use even if they don’t say anythong about FreeOTP. You can also attach icons to each token (do an image search and get them) which makes it visually easy to identify which token is which.

The app works well, exactly as it promises. I only miss the posibility of transfering the codes to another smartphone, and that the images that I asign to each number generator are lost from time to time.

Awesomeness!!!!!! Make sure you keep updating it. I love it.

Works well. No adaptive icon. No backup option.

Secure your digital life. With open source. From Red Hat.

Initially had Google Authenticator just because I needed to set up two-way authentication for RuneScape, and that was the authenticator that they recommended. Then I realized there were other apps (such as this one) that didn’t require 3rd party apps to work properly and that weren’t difficult to understand. This app is great so far and does just what I need it to do, but I only use it for scanning QR codes, so there’s that. The other stuff looks too complicated, lol.

A great authenticator app that’s free and open source and doesn’t require other apps to function. It doesn’t support exporting nor backup/syncing, but that’s a benefit in my opinion. Those types of features would make this less secure, defeating the point. I would recommend this to anyone who deeply cares about the security of their online accounts.
