FreeOTP
What FreeOTP is
FreeOTP is a free two-factor authentication app for Android and iOS. It generates one-time passwords using the HOTP and TOTP open standards, allowing compatibility with server-side systems that implement those protocols. Tokens can be added by scanning QR codes. The project recommends FreeIPA as a compatible server component, and the Google Play listing names Google, Facebook, Evernote, and GitHub among services that work with the app. Codes can be generated while a phone is in airplane mode. FreeOTP states that it does not collect data from the mobile device. Android camera access supports QR recognition and internet access supports token-image provisioning; neither permission is required. On iOS, token secrets are stored through Apple Keychain with the WhenUnlocked protection setting. Encrypted backups are required for iOS backup and restore, and locked tokens are excluded from device backups. Red Hat sponsors and officially publishes FreeOTP. The project accepts GitHub contributions under the Apache License 2.0 and lists a support email. The FreeOTP plan costs 0.00 USD and has no paid plans stated.
