Zero trust with zero clicks, a new take on IdPs

Tsidp is a lightweight OIDC/OAuth server that integrates with Tailscale's identity-first networking to streamline authentication processes by eliminating the need for repeated login prompts while enhancing security. It uses cryptographically guaranteed identities to authenticate users without additional actions, making it appealing for enterprises seeking to simplify access to local, SaaS, and AI applications. By utilizing device postures and access policy rules, tsidp consolidates network and application access management, ensuring secure resource access based on device attributes. Moreover, tsidp supports less common OAuth specifications, facilitating compliance with Model Context Protocol (MCP) deployments without the need to switch identity providers. This approach addresses common frustrations with frequent logins while maintaining robust security measures, making it a valuable tool for improving user experience and operational efficiency in corporate and experimental environments.
