Azure Storage Authentication Options
Azure Storage Authentication is the process of verifying the identity of a client that is requesting access to an Azure storage account. Azure Storage supports several authentication options that can be used to secure access to storage accounts, such as:
Shared Key Authentication: This method of authentication uses a shared key that is known to both the client and the storage account to sign request headers.
Shared Access Signature (SAS) Authentication: This method of authentication uses a shared access signature (SAS) token to provide restricted access to a storage account. A SAS token can be generated for a specific resource or set of resources within a storage account and can be used to grant read, write, or delete access to that resource.
Azure Active Directory (AAD) Authentication: This method of authentication allows you to secure access to a storage account using Azure AD. By connecting a storage account to Azure AD, you can use Azure AD authentication to grant access to specific users or applications that are already authenticated with Azure AD.
OAuth Authentication: This method of authentication allows you to authenticate with Azure Storage using an OAuth 2.0 Bearer Token. The token is passed in the Authorization header and is verified by Azure Storage.
Token-based Authentication: This method of authentication is an advanced authentication method and includes authentication with SAS, OAuth 2.0 bearer tokens and JSON Web Tokens (JWT)
Choosing the best authentication option depends on your requirements such as security, ease of use and ease of integration with existing systems or platforms. For example, for testing or development purposes, Shared Key authentication can be sufficient and easier to implement, but for production environments that requires high level of security or integration with enterprise environments you may prefer to use Azure AD or OAuth.
