# Keycloak Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

Keycloak is an open source Identity and Access Management solution aimed at modern applications and services, this document covers configuring Keycloak identity provider support with MinIO.

## Prerequisites

Configure and install keycloak server by following [Keycloak Installation Guide](https://www.keycloak.org/docs/latest/server_installation/#installing-the-software).
