#### Etcd

MinIO supports storing encrypted IAM assets in etcd, if KMS is configured. Please refer to how to encrypt your config and IAM credentials [here](https://github.com/minio/minio/blob/master/docs/kms/IAM.md).

This document explains the design approach of server side bucket replication. If you're looking to get started with replication, we suggest you go through the [Bucket replication guide](https://github.com/minio/minio/blob/master/docs/bucket/replication/README.md) first.

## Overview

- MinIO then checks if there are any policies [explicitly associated](#managing-usergroup-access-policy) with the user or their groups.
- On finding at least one associated policy, MinIO generates temporary credentials for the user storing the list of groups in a cryptographically secure session token. The temporary access key, secret key and session token are returned to the user.
- The user can now use these credentials to make requests to the MinIO server.
