TokenCredential Interface

The TokenCredential interface is a core component that allows for the implementation of custom authentication mechanisms. When you implement this interface, you can use it with Azure SDKs that accept credential objects for authentication. The code sample demonstrates how to create a custom credential class that extends TokenCredential.

class MyCredential extends TokenCredential {
  async getToken(scopes, options) {
    // Your logic to acquire a token
    return { token: 'your_token', expiresOnTimestamp: 12345 };
  }
}

DefaultAzureCredential

DefaultAzureCredential is a class that provides a seamless authentication experience across Azure services. It tries multiple credentials in a specific order, attempting to find the best one that works for the current environment. This code sample shows how to instantiate DefaultAzureCredential, which can then be passed to other Azure SDK clients for authentication.

const { DefaultAzureCredential } = require('@azure/identity');
const credential = new DefaultAzureCredential();
