@simplewebauthn/server

What is @simplewebauthn/server?

@simplewebauthn/server is a Node.js library that provides server-side functionality for WebAuthn, a web standard for secure authentication using public key cryptography. It helps in implementing registration and authentication flows for WebAuthn, making it easier to integrate strong, passwordless authentication into web applications.

What are @simplewebauthn/server's main functionalities?

Registration

This feature allows you to generate registration options for a new user and verify the registration response from the client. It ensures that the registration process is secure and follows the WebAuthn protocol.

const { generateRegistrationOptions, verifyRegistrationResponse } = require('@simplewebauthn/server');

// Generate registration options
const options = generateRegistrationOptions({
  rpName: 'Example Corp',
  rpID: 'example.com',
  userID: 'user-id',
  userName: '[e-mail]',
  attestationType: 'indirect',
  authenticatorSelection: {
    userVerification: 'preferred',
  },
});

// Verify registration response
const verification = verifyRegistrationResponse({
  credential: response,
  expectedChallenge: options.challenge,
  expectedOrigin: 'https://example.com',
  expectedRPID: 'example.com',
});

Authentication

This feature allows you to generate authentication options for an existing user and verify the authentication response from the client. It ensures that the authentication process is secure and follows the WebAuthn protocol.

const { generateAuthenticationOptions, verifyAuthenticationResponse } = require('@simplewebauthn/server');

// Generate authentication options
const options = generateAuthenticationOptions({
  rpID: 'example.com',
  userVerification: 'preferred',
});

// Verify authentication response
const verification = verifyAuthenticationResponse({
  credential: response,
  expectedChallenge: options.challenge,
  expectedOrigin: 'https://example.com',
  expectedRPID: 'example.com',
  authenticator: authenticator,
});
