Passport.js: how to access user object after authentication?

I'm using Passport.js to login a user with username and password. I'm essentially using the sample code from the Passport site. Here are the relevant parts (I think) of my code:


passport.serializeUser(function(user, done) {
done(null, user);

passport.deserializeUser(function(obj, done) {
done(null, obj);

passport.use(new LocalStrategy(function(username, password, done) {
User.findOne({ username: username }, function(err, user) {
if (err) {
return done(err);
if (!user) {
return done(null, false, { message: 'Incorrect username.' });
if (!user.validPassword(password)) {
return done(null, false, { message: 'Incorrect password.' });
return done(null, user);

passport.authenticate('local', { failureRedirect: '/login/fail', failureFlash: false }),
function(req, res) {
// Successful login
//console.log("Login successful.");
// I CAN ACCESS req.user here

This seems to login correctly. However, I would like to be able to access the login user's information in other parts of the code, such as:

app.get('/test', function(req, res){
// How can I get the user's login info here?
console.log(req.user); // <------ this outputs undefined

I have checked other questions on SO, but I'm not sure what I'm doing wrong here. Thank you!

You'll need to make sure that you register a middleware that populates req.session before registering the passport middlewares.

For example the following uses express cookieSession middleware

app.configure(function() {

  // some code ...

  app.use(express.cookieSession()); // Express cookie session middleware 
  app.use(passport.initialize());   // passport initialize middleware
  app.use(passport.session());      // passport session middleware 

  // more code ...
