Identity

Concept & How It Works

    Why Does It Exist?

    Without strong identity, agents run as anonymous super-users or share one API key. You cannot enforce RBAC, audit who did what, or revoke access when someone leaves the company.

    Real-World Analogy

    A corporate ID badge that also limits which doors open — not a shared master key taped under the reception desk.

    What is Identity?

    Example

    Scenario

    An employee opens the internal copilot; OIDC login yields a JWT with `groups: ['engineering']`. The agent uses that token to call GitHub as the user (not as a bot with org-wide admin) and only sees repos the user already has access to.

    Solution

    In Enterprise AI, apply Identity to this scenario: An employee opens the internal copilot; OIDC login yields a JWT with `groups: ['engineering']`. Identify the inputs, run the technique, validate the output, and note one thing you would monitor in production.

    Practice Task

    Do this before moving to the next module — reading alone is not enough.

    Open the Code Walkthrough below and run it locally. Change one parameter related to Identity (e.g. model, temperature, top_k, or tool name), observe the difference in output, and write 2–3 sentences explaining what changed.

    Commands to Remember

    Commands to Remember

    • pip install langchain chromadb # enterprise RAG stack
    • pip install python-jose # JWT identity tokens

    Common Mistakes

    • Treating Identity as a black box without evaluation
    • Ignoring cost and latency in production
    • Skipping error handling for identity
