SSO setup

Cal.com supports both Security Assertion Markup Language (SAML) and OpenID Connect (OIDC), two of the industry’s leading authentication protocols. We prioritize your ease of access and security by providing robust Single Sign-On (SSO) capabilities. Whether you’re looking for the XML-based standard of SAML or the lightweight OIDC, our platform is equipped to integrate smoothly with your preferred identity provider, ensuring both convenience and security for your users.
