Managed Identities: Passwordless Security

Hardcoding passwords in code is a major security risk. Azure Managed Identity is the modern fix — authenticate a Web App to a SQL Database without a single connection string or password.

Level: IntermediateCloud Computing

System-assigned vs user-assigned managed identities
Granting Azure RBAC roles to a managed identity
Passwordless connection from App Service to Azure SQL
Using DefaultAzureCredential in Python and Node.js
Accessing Key Vault secrets without a password
Auditing managed identity access with Azure Monitor
