Auth0 Social Connections

The Sovereign Gateway to Consumer Scale

Social Connections are the “Sovereign Gateway” to the consumer internet within the Auth0 ecosystem. They allow you to leverage the identity users already trust and use daily—Google, Facebook, GitHub, Apple, and more—to provide a “One-Click” registration and login experience. By integrating social logins, you drastically reduce Sign-Up Friction and improve User Retention while shifting the burden of password management and security to the world’s largest consumer identity providers. For the IAM architect, Social Connections are the engine of Engagement Sovereignty, ensuring that every user can access your platform instantly through the digital persona they already own.

Consumer Sovereign

Core Mission

Frictionless Consumer Onboarding. Establishing a robust, standards-based framework for integrating consumer social identities while maintaining centralized control over user profiles and application data.

Like a Global Membership Card: Imagine you are opening a high-end theme park (Your App). You could make everyone fill out a 20-page application form at the gate (Traditional Sign-Up). Or, you could just let them "Tap" the membership card they already keep in their wallet—like their "Global Passport" (Google) or their "Professional ID" (GitHub). They tap the card, the gate opens instantly, and you already know their name and email. The customer is happy because they didn't have to wait, and you are happy because you know exactly who entered.

The Social Strategy Matrix

Designing for social connections requires aligning the available providers with your application’s target demographic.

Strategic Social Profiles

Profile	Strategic Responsibility	IAM Implementation
Google / Apple	Universal Standard.	The highest adoption rates across mobile and web; ideal for general consumer apps.
GitHub / LinkedIn	Professional Identity.	Best for B2B developer tools, professional networks, and corporate landing pages.
Facebook / Twitter	Social Engagement.	Ideal for entertainment, news, and social media integrated applications.
Custom OAuth2	Niche & Specialized.	Connecting to smaller or proprietary social IdPs that use the standard OAuth2 protocol.

The Social Authentication Flow

A social login follows a “Consent-Exchange-Enrich” path between the user, the Social IdP, and Auth0.

1

Initiate the Social Handshake

The user clicks the social button on the Universal Login page. Auth0 redirects the user to the Social Idp (e.g. Google). Key to this step is the **Scope Request** (e.g. `openid profile email`). The social provider challenges the user to authenticate and then presents a **Consent Screen**, asking the user to authorize your app to access their data.

2

Trust Delegation & Verification

Once the user consents, the Social IdP sends an authorization code back to Auth0. Auth0 then exchanges this code for an **Access Token** from the social provider. Auth0 verifies the cryptographic integrity of the token, ensuring that the user's identity is "Sovereignly Confirmed" by the social giant.

3

Profile Normalization & Storage

Auth0 extracts the user's profile information (Name, Picture, Email) and **Normalizes** it into the standard Auth0 user profile. It creates (or updates) a local user record in your tenant. Your application then receives a standard Auth0 token. You never have to worry about the specific idiosyncrasies of the Facebook API or the GitHub profile format—Auth0 abstracts it all into a single, clean identity record.

Technical Social Implementation

Configuring a Google Social connection involves registering your ‘Client ID’ and ‘Secret’ in the Auth0 dashboard.

Social Connection Config (Conceptual UI)

# Configuring a Google Social connection
Connection_Name: "google-oauth2"
Strategy: "google-oauth2"
Config:
  ClientID: "google-developer-client-id"
  ClientSecret: "google-developer-client-secret"
  Allowed_Mobile_Clients: ["iOS-App-ID", "Android-App-ID"]
  Fetch_User_Profile_Data: true
  Attributes:
    - email
    - profile
