passport-auth0

This is the auth0 authentication strategy for Passport.js.

Installation

npm install passport-auth0

Configuration

Take your credentials from the settings section in the dashboard and initialize the strategy as follows:

var Auth0Strategy = require('passport-auth0'),
    passport = require('passport');

var strategy = new Auth0Strategy({
   domain:       'your-domain.auth0.com',
   clientID:     'your-client-id',
   clientSecret: 'your-client-secret',
   callbackURL:  '/callback'
  },
  function(accessToken, refreshToken, extraParams, profile, done) {
    // accessToken is the token to call Auth0 API (not needed in the most cases)
    // extraParams.id_token has the JSON Web Token
    // profile has all the information from the user
    return done(null, profile);
  }
);

passport.use(strategy);

State parameter

The Auth0 Passport strategy enforces use of state parameter in OAuth 2.0 authorization requests and requires session support in Express to be enabled.

If you require the state parameter to be omitted (which is not recommended), you can suppress it when calling the Auth0 Passport strategy constructor:

var Auth0Strategy = require('passport-auth0');

var strategy = new Auth0Strategy({
     domain: 'your-domain.auth0.com',
     // ...
     state: false
  },
  function(accessToken, refreshToken, extraParams, profile, done) {
    // ...
  }
);

Usage

app.get('/callback',
  passport.authenticate('auth0', { failureRedirect: '/login' }),
  function(req, res) {
    if (!req.user) {
      throw new Error('user null');
    }
    res.redirect("/");
  }
);

app.get('/login',
  passport.authenticate('auth0', {}), function (req, res) {
  res.redirect("/");
});

This way when you go to /login you will get redirected to auth0, to a page where you can select the identity provider.

If you want to force an identity provider you can use:

app.get('/login/google',
  passport.authenticate('auth0', {connection: 'google-oauth2'}), function (req, res) {
  res.redirect("/");
});

If you want to specify an audience for the returned access_token you can:

app.get('/login',
  passport.authenticate('auth0', {audience: 'urn:my-api'}), function (req, res) {
  res.redirect("/");
});

If you want to control the OIDC prompt you can use:

app.get('/login',
  passport.authenticate('auth0', {prompt: 'none'}), function (req, res) {
  res.redirect("/");
});

API access

If you want to get a list of connections or users from auth0, use the auth0 module.
