This episode of Techsplainers explores single sign-on (SSO), the authentication approach that lets users access multiple applications with just one login. Building on our previous authentication discussions, we explain how SSO balances security with convenience by eliminating the need for multiple passwords while enabling stronger authentication practices. The podcast walks through how SSO works technically and examines variations including adaptive SSO, federated identity management, and social login options. We also cover the technical standards powering SSO implementations, such as SAML, OAuth, and OpenID Connect. The episode concludes by addressing SSO's potential security risks and explaining why combining it with multi-factor authentication creates an ideal balance of convenience and protection.
