FreeOTP Authenticator

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 https://fedorahosted.org/freeotp for review or modification. Contributions are welcome!

Ratings and reviews

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

It works flawlessly. No updates required. For those who want a backup export feature - save original QR-code pictures (or resolve them into a string) for recovery and keep them in several secret places, one in Veracrypt container in a cloud, for example.

Ad-free and open source. The only thing that is missing: dark mode support FWIW, the fact that an OTP app doesn't support exporting the stored secrets should be considered a feature. Pro-tip: as a backup, every time you add an OTP code you also print out the QR code and store it in a secure location. However, the FreeOTP's internal OTP code database actually _can_ be backed up and restored using adb. This doesn't require a rooted device, enabling developer mode is sufficient.
