Single sign-on
Workspaces can use SAML 2.0 or OpenID Connect with Okta, Microsoft Entra ID, Google Workspace, and other identity providers. Members then choose Continue with SSO and sign in with their company account.
SSO only admits people who are already members or have an open invitation.
SCIM
With SCIM, your identity provider adds people to the workspace when they join the company, removes them when they leave, and keeps teams in step with your groups.
Setup steps for each provider are in the developer docs.
