  done(null, user.id);
});

passport.deserializeUser(function(id, done) { //Here you retrieve all the info of the user from the session storage using the user id stored in the session earlier using serialize user.
  db.findById(id, function(err, user) {
    done(err, user);
    });
});

passport.use(new LocalStrategy(function(username, password, done) {
