BrowserID authentication strategy for Passport and Node.js.
branch: master


Passport strategy for authenticating with BrowserID.

This module lets you authenticate using BrowserID in your Node.js applications. By plugging into Passport, BrowserID authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.


$ npm install passport-browserid


Configure Strategy

The BrowserID authentication strategy authenticates users using an assertion of email address ownership, obtained via the BrowserID JavaScript API. The strategy requires a validate callback, which accepts an email address and calls done providing a user.

passport.use(new BrowserIDStrategy({
    audience: ''
  function(email, done) {
    User.findByEmail({ email: email }, function (err, user) {
      return done(err, user);

Authenticate Requests

Use passport.authenticate(), specifying the 'browserid' strategy, to authenticate requests.

For example, as route middleware in an Express application:'/auth/browserid', 
  passport.authenticate('browserid', { failureRedirect: '/login' }),
  function(req, res) {
    // Successful authentication, redirect home.


This module is implemented based on the specifications being developed by Mozilla Identity, which remain a work-in-progress and are not final. Implementers are encouraged to track the progress of these specifications and update update their implementations as necessary. Furthermore, the implications of relying on non-final specifications should be understood prior to deployment.


For a complete, working example, refer to the signin example.
