Entra ID Token Refresh Library

Leverage cross-language libraries for seamless token refresh in Entra ID–authenticated applications.

What is Entra ID?

Entra ID (formerly Azure Active Directory) is a widely adopted identity platform for securing access to cloud applications and services. It uses a token-based authentication mechanism involving access tokens and refresh tokens to manage secure connections.

This open-source project provides libraries in Python, Java, C#, and JavaScript to automatically handle token expiration and refresh, ensuring uninterrupted connectivity to services like Azure Database for PostgreSQL Flexible Server.

Key Features

• Token Validation: Token validation before use and acquisition of new token if current token is invalid

• Connection Pool Integration: Token validation extends to new connections being created for connection pool

• Plug-in ecosystem: Pluggable architecture for different languages and frameworks

Supported Languages

• Python
• C#
• JavaScript
• Java (see note below)
