What Is SSO (Single Sign-On)?
SSO is an authentication method that lets users access multiple applications with one set of login credentials. After authenticating once (e.g., via Google Workspace or Okta), users can switch between connected apps without re-entering passwords. Common SSO protocols include SAML, OAuth 2.0, and OpenID Connect.
Also known as: single sign-on, SAML, OAuth
Why Does SSO (Single Sign-On) Matter?
SSO reduces password fatigue, improves security by centralizing authentication, and simplifies IT administration. For businesses evaluating SaaS products, SSO support is often a key requirement — though some vendors charge extra for it (sometimes called the 'SSO tax').
