FreeOTP Authenticator generates one-time passwords (OTPs) that add a second layer of security to your online accounts. These temporary codes are used in conjunction with your regular password to make logging in much more secure and difficult to hack.

Yes, FreeOTP Authenticator can generate one-time passwords even when your phone is in airplane mode or has no internet connection. The generation of OTPs is based on a shared secret and the current time, not on network connectivity.
It works with many popular online services like Google, Facebook, and GitHub. It also supports private corporate security systems that implement the standardized TOTP or HOTP protocols, such as FreeIPA.
Yes, FreeOTP Authenticator is completely free and open-source software. It is licensed under the Apache 2.0 license, meaning you can review and modify the source code.
