Firebase Authentication Microservice

Question

I am trying to write a REST microservice in Node.js that would deal with user authentication (among some other things) requests coming from different platforms.

What I would like is for the device to remember which user is signed in and keep the session for itself only. What currently happening is that I am able to login only one user at a time; if another user logs in from another device, the new user is returned as the currentUser. It's my first time using Firebase Authentication so I am very confused.

Here's the code for the login endpoint:

async signInUser( req, res, next ) {
    var user = firebase.auth().currentUser;

    if ( !user) {
        var email = req.body.email;
        var password = req.body.password;

        // sign user in: if login fails, send error message as response
        user = await firebase.auth().signInWithEmailAndPassword( email, password)
                        .catch( function( error) {
                            res.send( error.message);
                        });
    }
    // login successful: send user object as response
    res.send( user);        
}
