MinIO supports multiple admin users in addition to default operator credential created during server startup. New admins can be added after server starts up, and server can be configured to deny or allow access to different admin operations for these users. This document explains how to add/remove admin users and modify their access rights.

## Get started

When configured, MinIO sends request and credential details for every API call to an external HTTP(S) endpoint and expects an allow/deny response. MinIO is thus able to delegate access management to an external system, and users are able to use a custom solution instead of S3 standard IAM policies.
