title: Azure Blob Storage Data Source | Developer Documentation
description: Guide to configuring Azure Blob Storage as a data source in LlamaCloud, including UI, API, and client setup for multiple authentication methods.
---

Load data from Azure Blob Storage.

## Configure via UI

We can load data by using two different types of authentication methods:

## 1. Account Key Authentication Mechanism

## 2. Service Principal Authentication Mechanism

![azure\_blob](/_astro/az_service_principal.BIyvZ1KV_Z3RYR8.png)

## 3. SAS URL Authentication Mechanism

## Configure via API / Client
