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!

Very handy app. The low rating is due to the inability to migrate to a new device. There are several bugs related to, "I've exported my tokens but can't import them to the new device because it wants a password I don't have." It's not clear if the user ever setup a password in the first place. In short, there needs to be a mechanism to set the password on export. Related, the android "setup a new device from a previous device" feature does NOT copy over the key store so same issue.

Loved it. Still love it. My only concern is the lack of updates. Don't really care too much about not being able to export, there are a few different ways around that. However, versions of Android are keeping on. And with the most recent update of Android I've (unfortunately) finally started getting notifications this app was built for an older version of Android. Turns out it's a _much_ older version of Android. I can't risk it crapping out due to compatibility issues. Huge bummer.

WARNING If you use this app you may be unable to migrate to a new device. Some users report that if they create the backup file, when attempting to restore on a new device they are prompted for an unknown password and the import fails. There are reports of this problem going back months in the forums, but no fix. Unfortunate. I have used and recommended this app for years, but now that I have to upgrade my phone the only was to maintain access to my accounts is to re-register (in a new app)
