About this app

FreeOTP 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!

I've used this app for over a year without issue, and it has served me well. However, as noted by others, it's been a while since it's received an update. There is also no way to backup/retrieve secrets. As such, unfortunately, I've decided I should switch to andOTP, which appears to be current and actively developed as well as being capable of backups, etc., while still remaining free and open source

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.

Great! Very eay to setup and add authentication for different apps. I've tried adding security keys but I can't work out how to use it. Only bad thing is I can't scan my Yahoo! Mail authentication QR Code; I don't know if there is something wrong with the code or the app. The feedback/help link in the app goes to an inactive wiki page...
