microsoft-agents-authentication-msal
A msal-based authentication library for Microsoft Agents
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has low install friction, carries a permissive MIT license, and solves a concrete problem for anyone building agents with the Microsoft 365 Agents SDK that need to call Azure AD-protected services. No known vulnerabilities. Install it if you are using the Microsoft Agents framework and need to authenticate with Azure resources.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >= 3.10 and valid Azure AD credentials (client ID, secret/certificate, and tenant ID) configured via environment variables.
- Low friction install with three runtime dependencies.
- Active maintenance: released 15 days ago, last commit 2026-08-13, repository has 1036 stars and is not archived.

What it is and what it does
This package wraps Microsoft Authentication Library (MSAL) to provide authentication for agents built with the Microsoft 365 Agents SDK. It abstracts the complexity of obtaining and refreshing OAuth tokens from Azure AD, enabling agents to authenticate securely when calling Microsoft services like Teams, Microsoft Graph, and other Azure resources.
The library supports multiple authentication types (client secret, certificate, managed identity) and is designed to integrate with the broader Microsoft Agents framework. It handles token caching and multi-tenant scenarios, allowing agents to operate across different Azure AD tenants. The package is part of a larger SDK ecosystem for building enterprise conversational AI agents.
Use it for
- Authenticate a Teams bot or agent to call Microsoft Graph API on behalf of the organization.
- Enable secure agent-to-agent communication within an enterprise Azure AD tenant.
- Use managed identity authentication in Azure-hosted agents to avoid storing secrets.
- Implement on-behalf-of (OBO) flow so agents can act on behalf of signed-in users.
- Build multi-tenant agents that work across different Azure AD organizations.
