FreeOTP provides an additional layer of security for your online accounts. It enhances your login by generating one-time passwords on your mobile devices, which, when combined with your regular password, significantly reduces the risk of hacking. Remarkably, these passwords can be generated even when your phone is in airplane mode.

FreeOTP seamlessly integrates with numerous popular online services such as Google, Facebook, Evernote, GitHub, and many others. It also extends its support to private corporate security if they have implemented the standardized TOTP or HOTP protocols. Notably, FreeIPA, a leading enterprise solution, is also compatible with FreeOTP.

Moreover, one of the remarkable aspects of FreeOTP is that it is open-source and completely free software. It operates under the Apache 2.0 license and provides you with the opportunity to review and modify its source code. Contributions to the project are highly encouraged and warmly welcomed.
