Configure email sign-in

  1. Go to the Identity Providers page in the Cloud Console.

    Go to the Identity Providers page

  2. Click Add A Provider.

  3. Select Email/Password from the list of providers and enterprise federation standards.

  4. Toggle the Enabled switch to On.

  5. Click Save.

Create a user

  1. Go to the Users page in the Cloud Console.

    Go to the Users page

  2. Click Add user.

  3. Enter an email and password.

  4. Click Save. The new user appears in the users list.

Sign the user in

  1. Create a new file named index.html.

  2. Add two basic HTML containers:

    <div>Identity Platform Quickstart</div>
<div id="message">Loading...</div>

  3. Initialize the Identity Platform Client SDK with your API key:

    1. Go to the Identity Providers page in the Cloud Console.

      Go to the Identity Providers page

    2. Click Application setup details.

    3. Copy the initialization code into index.html. It should look something like:

      <script src="https://www.gstatic.com/firebasejs/7.14.6/firebase.js"></script>
<script>
  // Initialize Identity Platform
  var config = {
    apiKey: "abcdefg123456",
    authDomain: "myproject.firebaseapp.com"
  };
  firebase.initializeApp(config);
</script>

  4. Sign the user in by calling signInWithEmailAndPassword(), and then process the result with the onAuthStateChanged() callback. In the example below, replace email and password with the values for the user you created earlier:

    <script>
  var email = "example@gmail.com";
  var password = "hunter2";

  firebase.auth().onAuthStateChanged(function(user) {
    if (user) {
      document.getElementById("message").innerHTML = "Welcome, " + user.email;
    } else {
      document.getElementById("message").innerHTML = "No user signed in.";
    }
  });

  firebase.auth().signInWithEmailAndPassword(email, password).catch(function(error) {
    document.getElementById("message").innerHTML = error.message;
  });
</script>

  5. Launch index.html in your web browser. A welcome message displaying your user's email appears.

Congratulations! You've signed your first user in with Identity Platform.

What's next

In a real app, your users would sign up using a dedicated registration page, and sign in by entering their emails and passwords. Identity Platform offers a pre-built authentication UI you can use for these pages, or you can build your own. You might also want to support additional sign-in methods, such as social providers (like Facebook or Google), phone numbers, OIDC, or SAML.
