Federated identity
Federated identity is an authentication and identity management approach that allows users to access multiple systems, applications, or organizations using a single set of credentials. In a federated identity system, users authenticate once with their identity provider (IdP), such as Google, Microsoft, or Facebook, and then gain access to various resources without needing to log in again.
Federated identity is commonly implemented using standards like SAML (Security Assertion Markup Language), OAuth, or OpenID Connect, which enable secure sharing of authentication and identity information between different systems or domains. This approach enhances user experience by reducing password fatigue, minimizes security risks from managing multiple credentials, and simplifies identity management for administrators.
Federated identity is widely used in enterprise environments for single sign-on (SSO) solutions, as well as in cloud-based applications, allowing seamless access across platforms and organizations.
How CodeBranch applies Federated identity in real projects
The definition above gives you the concept — but knowing what Federated identity means is different from knowing when and how to apply it in a production system. At CodeBranch, we have spent 20+ years building custom software across healthcare, fintech, supply chain, proptech, audio, connected devices, and more. Every entry in this glossary reflects how our engineering, architecture, and QA teams actually use these concepts on client projects today.
Our work combines AI-powered agentic development, the Spec-Driven Development (SDD) framework, CI/CD pipelines with agent rules, and production-grade quality gates. Whether you are evaluating a technology for your product, trying to understand a vendor proposal, or simply learning, this glossary is written to give you practical, accurate context — not theoretical abstractions.
