Enterprise customers offer significant growth potential for B2B applications but present unique challenges, such as onboarding a large user base efficiently. Integrating Secure Assertion Markup Language (SAML), a single sign-on standard, with verified domains can automate and streamline this process, enhancing user experience and reducing support workload. SAML facilitates secure communication between systems by sharing user details and supports Just-in-Time (JIT) Provisioning, allowing flexible attribute mapping. When configured with a SAML connection, users logging in with associated email addresses are prompted to authenticate using their enterprise identity provider, simplifying access. Verified domains enable automatic enrollment of users from large corporations into applications, allowing them to use their existing work credentials for immediate access. The article provides a detailed guide for configuring SAML with Google Workspaces and setting up verified domains within organizations using the Clerk platform, ultimately simplifying and accelerating the onboarding process for enterprise customers.
