About

Admin API keys grant programmatic access to organization and compliance APIs outside an interactive browser session. An attacker who creates one after compromise can automate role grants, exports, and logging changes without holding a user session that would time out under SSO. The key also survives password resets and IdP lockout if defenders revoke the interactive account but miss the API credential.
