Firebase - Email Authentication

In this chapter we will show you how to use Firebase Email/Password authentication.

Create user

To authenticate user, we can use createUserWithEmailAndPassword(email, password) method.

Example

var email = "myemail@email.com";
var password = "mypassword";

firebase.auth().createUserWithEmailAndPassword(email, password).catch(function(error) {
   console.log(error.code);
   console.log(error.message);
});

We can check Firebase dashboard and see that user is created.

Sign In

Sign in process is almost the same. We are using signInWithEmailAndPassword(email, password) to sign in user.

Example

var email = "myemail@email.com";
var password = "mypassword";

firebase.auth().signInWithEmailAndPassword(email, password).catch(function(error) {
   console.log(error.code);
   console.log(error.message);
});

Signout

And finally we can logout user with signOut() method.

Example

firebase.auth().signOut().then(function() {
   console.log("Logged out!")
}, function(error) {
   console.log(error.code);
   console.log(error.message);
});
