How do I implement social login for my web app?

Social login allows users to access web applications using existing credentials from identity providers like Google, GitHub, and Apple, reducing the friction of account creation. This authentication method relies on OAuth 2.0 and OpenID Connect (OIDC) protocols, where the application delegates authentication to a trusted third party and receives verified identity data in return. Social login is significant because it simplifies user onboarding, as research indicates that account creation is a major barrier to user engagement, with 19% of users abandoning purchases due to forced account creation. It also enhances security by offloading password management to providers with robust security infrastructures. Implementing social login involves understanding the protocols, selecting suitable identity providers, and managing security concerns like PKCE and state parameters to prevent attacks. Providers differ in setup complexity, data returned, and audience served, with Google being the most prevalent, accounting for approximately 75% of social logins. The choice of providers should be limited to avoid user confusion, typically maintaining 2–3 options, and alternative authentication methods should be offered for users opting out of social login. Clerk simplifies social login integration across various frameworks and native mobile platforms, emphasizing security through automatic mechanisms such as account linking with verified emails and a hybrid token architecture that combines stateful revocation with stateless JWT verification.
