Here’s a simple example:Īs previously mentioned, the connection string doesn’t contain a username or a password, only the Azure SQL instance and database we want to connect to. The authentication is performed via an access token that we associate with the SQL connection.Īcquiring the token is done with the help of the Azure.Identity NuGet package through the DefaultAzureCredential class. The killer feature of that class is, that it tries to acquire an access token from different sources, including: Connecting to Azure SQL using Azure Active Directory authenticationĪs mentioned before, this approach doesn’t use the traditional way of having a connection string that contains a username and a password. Instead, the credentials are replaced with an access token, much like you would use when you call an API.

In this post, we’ll talk about how one can connect to Azure SQL using token-based Azure Active Directory authentication, and how to do so using Entity Framework Core. After all, isn’t the best password one that doesn’t exist in the first place? The main benefit comes from the fact that we don’t need to manage and protect the credentials required to connect to the database. We think this is more secure, because the less sensitive information to protect, the less chance of them being accessed by unauthorised parties. Acquire a token from Azure Active Directory, and use it to establish the connection to the database.Grant the necessary permissions to this identity on the target Azure SQL database.If not done already, assign a managed identity to the application in Azure.Instead of using a connection string that contains a username and a password, we’re using the following strategy: In the case of Azure SQL, however, we’re using a slightly different technique, by leveraging Azure Active Directory authentication, and more specifically token-based authentication. One aspect of this is how we deal with sensitive information, like database connection strings, API keys, or AAD client secrets. The approach we’re using is to store these in Key Vault instances, which can be accessed by the applications that require them, thanks to Azure managed identities. We’re trying to improve the security posture of our internal applications.
