The toolkits are trusted authentication libraries used by startups and enterprises alike.

But security doesn't happen in a vacuum. Vulnerabilities in authentication libraries can have widespread consequences. Maintaining open-source security requires continuous effort, expertise, and funding. By supporting SAML-Toolkits, you’re not just securing your own systems—you’re strengthening auth security globally.

How you can help

• Sponsor SAML-Toolkits: GitHub Sponsors
• Contribute to secure-by-design improvements.
• Responsibly report vulnerabilities.

Security is a shared responsibility. If the SAML open source toolkits have helped your organization, please consider giving back. Together, we can keep authentication secure.
