The Developer’s Guide to SSO

Single Sign-On (SSO) is a security feature that allows users to authenticate through an external service, reducing the need for multiple usernames and passwords. It can increase engagement by lowering signup friction and retention through smoother login flows. SSO works with protocols like SAML, OAuth, WS-Fed, and OpenID Connect. To add SSO to your app, you can build it from scratch or use a third-party service like WorkOS, Auth0, AWS Cognito, or GCP Identity Platform. Best practices for integrating SSO include enforcing security measures, optimizing routing, and improving user experience.
