Alternatives to FreeOTP
Red Hat's minimal open source OTP
FreeOTP ranks #8 of 10 in Authenticator apps, with an Alt Score of 55. It is licensed under Apache-2.0, free and available on iOS and Android. 6 of 9 checklist rows are verified against a public source.
Individuals and organizations who want a free, open-source two-factor authentication app instead of a proprietary one, on either iOS or Android.
FreeOTP generates TOTP and HOTP one-time passwords using open standards, so it works with any server implementing those protocols without a proprietary server-side component. It's open source under the Apache License 2.0 and developed by Red Hat. A companion QR code generator tool is available for services that need to provision tokens.
Add an account by scanning the QR code your service provides (or entering the setup key manually); FreeOTP then generates a time-based or counter-based one-time code you enter when logging in.
