FreeOTP is a free and open-source software token that can be used for two-factor authentication.[3][4][5] It provides implementations of HOTP and TOTP. Tokens can be added by scanning a QR code or by manually entering the token configuration. It is maintained by Red Hat under the Apache 2.0 license, and supports Android and iOS.[6]

FreeOTP Plus (aka FreeOTP+) is a fork of FreeOTP with enhancements including exporting and importing settings.[7][8][9][10]
