OSIAM - Open Source Identity and Access Management Circle CI Codacy Badge Codacy Badge

Active development of this project has stopped.

OSIAM is a secure identity management solution providing REST based services for authentication and authorization. We achieve this by implementing two important open standards:

OSIAM is published under the MIT licence, giving you the greatest freedom possible to utilize OSIAM in you project or product. Watch our blog to stay informed about releases and upcoming changes.

Use cases

  • [Single app with OSIAM](docs/single-app-use-case.md) as free backing store for users and groups and local auth service.
  • [Distributed app with OSIAM](docs/distributed-app-use-case.md) as central identity store and auth service.
  • [Publish your app's API with OSIAM](docs/protected-api-use-case.md) as auth service for 3rd-parties and allow safe access to your user's data.

Quick Start

Download the latest version of OSIAM:

curl -L https://dl.bintray.com/osiam/downloads/osiam/3.0/osiam-3.0.war -o osiam.war

Make the .war file executable:

chmod +x osiam.war

Start OSIAM:


After some seconds, OSIAM should be fully running. You can now retrieve your first access token:

curl -H "Authorization: Basic ZXhhbXBsZS1jbGllbnQ6c2VjcmV0" -X POST -d "grant_type=client_credentials&scope=ADMIN" http://localhost:8080/oauth/token

You can now start to setup OSIAM, by changing the administrator's password and add your own OAuth client. Please see the [Installation and Configuration Manual](docs/detailed-reference-installation.md#customize-setup) for details.


Learn how to install and configure OSIAM for production in the [documentation](docs/README.md).


  • osiam handles the authentication and authorization based on OAuth 2.0 and holds the SCIM based user data
  • addon-self-administration provides account management self-service as a web application
  • addon-administration lets you administer users and groups via a web application
