Entra App Registration

A comprehensive guide for setting up Microsoft Entra ID app registrations and OAuth flows. Walks you through creating app registrations via portal, CLI, or Bicep templates, configuring authentication for different app types (web, SPA, mobile, daemon), and implementing MSAL integration with working console app examples. Covers the full workflow from initial registration to API permissions, client secrets, and service principal creation. The security best practices section is solid, emphasizing certificate-based auth over secrets and proper token validation. Really shines when you need to quickly spin up authentication for Azure-integrated apps or explain OAuth flows to teammates.
