Integrating other authentication/authorization providers like Google, Facebook, X (Twitter), GitHub, etc. is also possible and relatively easy.

The most complex problem is building an authentication/authorization provider like those, but **FastAPI** gives you the tools to do it easily, while doing the heavy lifting for you.

# KMS IAM/Config Encryption

MinIO supports encrypting config, IAM assets with KMS provided keys. If the KMS is not enabled, MinIO will store the config, IAM data as plain text erasure coded in its backend.

## MinIO KMS Quick Start

MinIO supports two ways of encrypting IAM and configuration data.
You can either use KES - together with an external KMS - or, much simpler,

   * href="http://www.w3.org/TR/html4/">HTML 4.01</a>. The resulting strings can be used both in
   * attribute values and in most elements' text contents, provided that the HTML
   * document's character encoding can encode any non-ASCII code points in the input (as UTF-8 and
   * other Unicode encodings can).

## Introduction

MinIO provides a custom STS API that allows authentication with client X.509 / TLS certificates.

But at some point, there was no other option than creating something that provided all these features, taking the best ideas from previous tools, and combining them in the best way possible, using language features that weren't even available before (Python 3.6+ type hints).
