Auth0 login alone does not limit which records an agent can retrieve. The first installment of Auth0’s tutorial demonstrates user authentication and passes identity context into an expense-report agent, but it uses hardcoded sample reports and does not yet filter them by manager.
What the Auth0 and Microsoft Agent Framework tutorial builds
Auth0 Principal Developer Advocate Andrea Chiarelli’s August 3, 2026 tutorial builds a server-side Blazor expense-approval assistant using Microsoft Agent Framework, Auth0 authentication, and Azure AI Foundry as the model host. The example deploys gpt-4.1-mini through Azure AI Foundry; that is the tutorial’s dated example, not a general model recommendation.
The application uses an AIAgent built on an IChatClient-compatible service, exposes a GetExpenseReports() function tool, and serializes conversation session state to a cache under a per-user session key. The tutorial describes Microsoft Agent Framework as succeeding Semantic Kernel and AutoGen, with agents, tools, and persistent sessions as central concepts. [Auth0 tutorial]
Its prerequisites are the .NET 10 SDK, an Auth0 CLI and account, an Azure account with an Azure AI Foundry resource, and basic Blazor familiarity. The template scaffolds a Blazor Web App with Auth0 authentication and login/logout routes.

How identity should flow from login to data
Authentication answers “who is signed in?” Authorization answers “which records and actions may this identity access?” Keep those decisions separate. In the tutorial, the application reads the authenticated user’s Auth0 identifier, passes it into the agent’s tool object, and uses the identifier for the session key. But the sample tool’s manager ID is not yet applied to filter expense reports: its data is hardcoded for this installment.
That distinction matters because an agent can only be as constrained as the tools it can call. A secure data path should apply authorization before returning records to the model:

- Authenticate the person or service. Establish the identity through an appropriate Auth0 flow.
- Carry the identity into the application. Pass verified user or workload context to the agent and its tools rather than relying on a prompt or conversation text to identify the actor.
- Authorize at the tool or data boundary. Check that identity’s permitted scope before retrieving records or executing an action.
- Return only authorized data. Do not send unauthorized records to the model and depend on it to ignore them.
- Keep conversation state scoped. The tutorial keys serialized session state by user ID, helping keep one user’s conversation state distinct from another’s.
The tutorial says a later installment will add Auth0 Fine-Grained Authorization (FGA) so managers see expenses for their direct reports, replacing the sample’s hardcoded reports with a vector database and manager-scoped retrieval. That planned capability is not enforced by the first installment.
Choose authentication for the agent’s actor
Decide whether a request represents a person using an agent or an autonomous agent acting as a service. Microsoft distinguishes interactive agents that act for a signed-in person through delegated permissions from autonomous agents that use their own identity. Auth0 documents user authentication, machine-to-machine authentication, and delegated authorization for agents. [Microsoft Entra security for AI overview] [Auth0: User Authentication for AI Agents]

| Situation | Identity pattern | What to verify |
|---|---|---|
| A signed-in person asks an agent to act within that person’s authority | Delegated access: the agent acts on behalf of the user. Auth0 describes on-behalf-of token exchange and Token Vault patterns for delegated access. | Constrain access to the user’s approved scope; check authorization for each resource or operation. |
| An autonomous agent or backend acts as itself | Machine-to-machine authentication with its own workload identity. Auth0 documents client credentials, mTLS, and Private Key JWT options. | Grant only the resources and actions the service needs; identify an owner and a revocation path. |
Do not choose a machine identity simply because an agent runs in the background: if it is carrying out a user’s request, delegated authorization may be the relevant model. Conversely, a service doing scheduled work on its own behalf needs a distinct workload identity rather than a borrowed human login.
Choose a login experience without confusing it with authorization
For a user-facing application, Auth0 recommends Universal Login: the user is sent to a hosted login page, so the application does not directly handle the user’s credentials. Embedded login gives the application more control over the interface, but the application team must handle credential input and secure communication; Auth0 describes it as more complex to maintain.

| Consideration | Universal Login | Embedded login |
|---|---|---|
| Credential handling | Credentials are entered on Auth0’s hosted login page, not directly in the application. | The application handles credential input and secure communication. |
| Customization | Less direct control of the login UI than an embedded flow. | More control over the UI. |
| Implementation and maintenance | Auth0 recommends this approach for login UX. | More complex to maintain, according to Auth0. |
| Typical context | User-facing sign-in where the application should avoid handling credentials directly. | A case where tighter UI control is needed and the team can take on credential-handling responsibilities. |
Neither login choice establishes which expense reports the resulting agent may access. That still depends on the authorization checks in the application and its data tools.

Agents can introduce risks such as prompt injection, external exposure, and permission escalation, according to Microsoft’s overview of security for AI. A trusted login does not neutralize those risks; permissions should be bounded independently of what a user or model asks an agent to do. [Microsoft Entra security for AI overview]

Microsoft’s least-privilege guidance recommends unique agent identities with owners, reviews of effective permissions, denying unreviewed tools by default, detailed logging, and testing disablement and credential or token revocation. [Microsoft: Least privilege for AI agents with Microsoft Entra Agent ID]
- Assign a unique identity and owner. Avoid unclear shared credentials; make it possible to identify who is responsible for an agent.
- Review effective access. Check what the agent can actually reach, including permissions inherited through its tools and connected services.
- Allowlist tools. Deny tools that have not been reviewed, and keep the available tool set narrow.
- Gate consequential actions. Require approval or time-limited elevation for high-impact operations instead of granting standing broad access.
- Log for investigation. Record identity, scope, action, and correlation details so activity can be traced across the application and its services.
- Test revocation. Verify that disabling an identity and revoking its credentials or tokens stops access promptly.
For each agent capability, ask four questions: who is acting (the user or the agent’s own identity); which data and actions are authorized; which tools are approved and whether sensitive actions require approval; and whether logs support investigation and access can be revoked quickly.
Try the tutorial’s expense-report prompts
The tutorial’s sample prompt is “Show me the pending expense reports.” It also suggests asking, “Which ones are missing information?” These are useful examples for exploring the agent’s conversation, but prompts are not access controls: the application must authorize the data returned by its tools.
