2FA + WebAutN

Basic two-factor authentication requires a user to provide two forms of identity to gain access to a protected resource or data. After supplying the username and password, the app sends the user a confirmation code through SMS or Email. The user must enter that confirmation code before the system signs them into the app.

The two-factor authentication with WebAuthN workflow uses an alternative to the confirmation code method. The alternative is to use an authenticator.

An authenticator is a device such as a PC, mobile phone, or tablet that can:

  • Set up a private/public key pair
  • Locally confirm consent by a user


How It Works

Now that Express has a public key credential for the authenticator, subsequent sign-ins use the authenticator as a second factor:

In terms of the OpenID Connect (OIDC) specifications, the Web App is the Relying Party, and the ForgeRock Identity Cloud is the Authorization Server. See The OpenID Foundation Specifications.
