SDK example

Connect the browser SDK via script tag (UMD). Full snippets and JWT verification — in the documentation.

<script src="https://id.example.com/browser/auth-bots.umd.js"></script>
<script>
  AuthBots.init({
    appId: 'YOUR_APP_ID',
    baseUrl: 'https://id.example.com'
  });

  // Popup login
  document.getElementById('login-btn').addEventListener('click', function () {
    AuthBots.login({ mode: 'popup' }).then(function (result) {
      console.log('JWT:', result.token);
    });
  });

  // Or embedded widget (same SDK):
  AuthBotsWidget.init({
    app_id: 'YOUR_APP_ID',
    base_url: 'https://id.example.com',
    poll_type: 'full',
    button_text: 'Sign in',
    theme_color: '#1976d2'
  });
</script>
<button id="login-btn" type="button">Sign in</button>

Architecture

Your site talks to Auth Cloud; users confirm in a messenger; your backend verifies JWT via JWKS.

Your siteAuth CloudMessengers
JWT (RS256)Your API

Why teams choose it

🚀

No SMS bill

Users confirm login in a messenger. No per-SMS cost for authentication.

🔐

JWT + JWKS

Short-lived RS256 token and a single JWKS endpoint for your services.

🤖

Per-application bots

Each client app has its own messenger credentials and widget settings.

📨

Notifications

Message API and delivery logs for users who signed in through your bots.

Cost per login
