--- title: "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. ### Setting up SAML login Follow the instructions here - [SAML Setup](/developing/guides/auth-and-provision/sso-setup#saml-registration-with-identity-providers) Ensure that all users who need access to Cal.com have access to the IdP SAML app. Keep the XML metadata from your IdP accessible, as you will need it later. Visit `settings/organizations/sso`. Click on the `Configure` button for `SSO with SAML`. In the SAML configuration section, copy and paste the XML metadata from step 3 and click on Save. Once setup is complete, provisioned users can log into Cal.com using SAML. ### SAML Registration with Identity Providers This guide explains the settings you need to use to configure SAML with your Identity Provider. Once configured, obtain an XML metadata file and upload it on your Cal.com instance. > **Note:** Please do not add a trailing slash at the end of the URLs.
