    Ruby One Time Password library

  • Aside from SMS scams, SMS is the least secure type of 2FA. I recommend implementing OTP via authenticator apps like Authenticator and 1Password. You can use the rotp gem for this: https://github.com/mdp/rotp

  • identity-idp

    Login.gov Core App: Identity Provider (IdP)

  • For more advanced 2FA techniques, including security keys, take a look at the source code for login.gov: https://github.com/18F/identity-idp

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
