  • Resource friendly. Small memory footprint.
  • Enables partial to complete compliance with various bodies of rules and laws including HIPAA, GDPR, PCI. Work in progress to achieve complete compliance.

SSO Clients

Getting Started

The fastest way to get started without reading a lot of documentation is to download/'git pull' the server from this repository and a SSO client from the list above and then follow along with the four part video tutorial series:

SSO server/client tutorial series

And use the installation documentation as necessary.

According to users of this software, it takes about 3 hours to get a functional SSO server/client setup for the first time. Building an equivalent system from scratch would take approximately six months for a team of several people, have less flexibility, and probably have multiple security vulnerabilities.
