Close added a Security page under organization settings that groups access controls in one place. Admins can set up single sign on through Google Workspace or any OIDC provider such as Okta or Microsoft Entra and require it for everyone on verified domains, require app based two factor authentication for password sign ins, and decide whether Close support staff may log in to the organization. Custom OIDC requires the Scale plan or above.
Small and mid sized sales teams get enforced single sign on and control over vendor support access, two checks that often hold up a security review.
