Janssen Project is a distribution of digital identity components that enables large organizations to self-host an identity federation service which supports high concurrency, multi-cloud deployments and has the flexibility to solve almost any custom functional requirements. It is used for person authentication, web single sign-on, mobile authentication and for OAuth-based API access management. Janssen is not one piece of software--like Linux, it's a distribution of software , all of which is community-governed and published under a permissive open source license.
