SSO

Single Sign-On (SSO) is an authentication scheme that allows users to log in once and gain access to multiple related applications without re-entering credentials. Enterprise SSO typically uses SAML or OIDC/OAuth 2.0 protocols, with an identity provider (IdP) like Okta or Azure AD issuing tokens. SSO reduces password fatigue and centralized authentication makes it easier to enforce MFA and deprovisioning. It is a compliance requirement in many enterprise security frameworks.
