Single Sign-On (SSO)
Definition
An authentication scheme that allows users to log in once and access multiple related systems without re-authenticating.
Overview
Single Sign-On (SSO) enables users to authenticate once and access multiple applications without additional logins. SSO improves user experience, reduces password fatigue, and centralizes authentication for better security control. Common SSO protocols include SAML and OAuth/OIDC. SSO is typically implemented through an identity provider (IdP) like Okta, Azure AD, or OneLogin. SSO integration is often a requirement for enterprise software adoption.
Why It Matters
Without SSO, employees manage dozens of passwords—leading to weak credentials, password reuse, and IT help desk overload. SSO centralizes authentication, reduces the attack surface, and is a baseline enterprise security requirement that gates software procurement decisions.
How New Odyssey Helps
New Odyssey supports SSO via SAML and OAuth/OIDC out of the box, integrating with major identity providers like Okta and Azure AD to ensure seamless, secure authentication for every user.
