To prototype SSO on a startup website, start by selecting a popular authentication provider such as Google, Facebook, or Auth0. Next, integrate their OAuth or OpenID Connect APIs to allow users to log in using existing accounts. Implement a simple login button on your site that redirects users to the provider's sign-in page. Ensure you handle token validation on your backend to maintain security. Additionally, use mock user data initially to test the flow before connecting with a real database. Finally, collect user feedback to refine the authentication experience for your startup.
