# Provisioning users with SCIM

System for Cross-domain Identity Management (SCIM) is an open standard protocol that automates the exchange of user identity information between an identity provider (IdP)—such as Microsoft Entra ID or Okta—and a target application like Cortex. It defines a standard schema and REST API for creating, updating, and deprovisioning user accounts, eliminating the need for manual account management. IT administrators and DevOps teams commonly use SCIM to manage user lifecycles at scale across multiple applications from a single source of truth. By automating user provisioning and deprovisioning, SCIM reduces the risk of human error, ensures access is granted and revoked in a timely manner, and frees up administrators from repetitive manual tasks, making it especially valuable in organizations with large or frequently changing user bases.

Cortex supports SCIM provisioning from [Okta](https://docs.cortex.io/configure/settings/managing-users/provisioning-users-with-scim/okta-scim) and [Microsoft Entra ID](https://docs.cortex.io/configure/settings/managing-users/provisioning-users-with-scim/entraid-scim).
