In this tutorial, you'll learn about Auth0 Social Login. We cover key concepts, practical examples, and best practices to help you understand and apply this topic effectively.

Auth0 social login enables users to authenticate with their existing social accounts for frictionless registration.

// Social connections configuration
const connections = await auth0.connections.create([
  {
    name: 'google-oauth2',
    strategy: 'google-oauth2',
    options: {
      client_id: process.env.GOOGLE_CLIENT_ID,
      client_secret: process.env.GOOGLE_CLIENT_SECRET,
      scopes: ['email', 'profile'],
      email: true
    }
  },
  {
    name: 'apple',
    strategy: 'apple',
    options: {
      client_id: process.env.APPLE_CLIENT_ID,
      team_id: process.env.APPLE_TEAM_ID,
      key_id: process.env.APPLE_KEY_ID,
      private_key: process.env.APPLE_PRIVATE_KEY
    }
  }
]);

// Account linking via Actions
exports.onExecutePostLogin = async (event, api) => {
  if (event.user.identities.length > 1) return;

  const existingUser = await api.user.getByEmail(event.user.email);
  if (existingUser && existingUser.user_id !== event.user.user_id) {
    await api.user.linkAccount(event.user.user_id, existingUser.user_id);
  }
};

Social login increases conversion rates by eliminating password creation and reducing registration friction.
