#### 1. Initialize
An example configuration which reads the JWT from the http
Authorization header with the scheme 'bearer':

- : unique identifier of your firebase project.

`js
const FirebaseStrategy = require('passport-firebase').Strategy;
const opts = {};
opts.issuer = 'https://securetoken.google.com/';
opts.audience = '';
passport.use(new FirebaseStrategy(opts, function(jwt_payload, done) {
User.findOne({id: jwt_payload.sub}, function(err, user) {
if (err) {
return done(err, false);
}
if (user) {
return done(null, user);
} else {
return done(null, false);
// or you could create a new account
}
});
}));
`

#### 2. Authenticate requests

Use passport.authenticate() specifying 'firebase' as the strategy.

`js
app.post('/profile', passport.authenticate('firebase', { session: false }),
function(req, res) {
res.send(req.user.profile);
}
);
`
