adal
Note: This library is already replaced by MSAL Python, available here: https://pypi.org/project/msal/ .ADAL Python remains available here as a legacy. The ADAL for Python library makes it easy for python application to authenticate to Azure Active Directory (AAD) in order to access AAD protected web resources.

Before you install
- Requires valid Azure AD tenant and credentials; the package is no longer maintained.
- Installation is straightforward with low friction, but the package is abandoned as of 2021-04-05 and the repository is archived.
- Microsoft explicitly recommends migrating to MSAL for new projects.

- Compatibility with modern Python versions beyond 3.6, given classifiers only list up to Python 3.6.
What it is and what it does
ADAL for Python is a legacy authentication library that enables Python applications to authenticate with Azure Active Directory and retrieve tokens for accessing Azure AD-protected web resources. It handles OAuth2 and OpenID Connect flows, supporting scenarios like native client applications and web applications that need to call APIs such as the Graph API. The library depends on PyJWT, requests, python-dateutil, and cryptography.
The package is no longer maintained and has been superseded by MSAL for Python. While existing applications using ADAL will continue to work, Microsoft explicitly directs new projects to use MSAL instead. The repository is archived and the latest release was 2021-04-05.
Use it for
- Maintaining or updating legacy Python applications that already authenticate with Azure AD via ADAL.
- Migrating from ADAL to MSAL by using ADAL as a reference during the transition process.
- Understanding historical Azure authentication patterns in Python codebases that predate MSAL adoption.
