Authentication and security
Secure .NET apps with Identity, JWT and best practices.
📖 Key ideas
- ASP.NET Core Identity manages users, passwords and roles.
- JWT bearer authentication for APIs.
- [Authorize] protects endpoints; policies define rules.
- Data Protection API encrypts cookies and tokens.
- Keep secrets in user-secrets, environment variables or Key Vault.
💡 Real-life example: [Authorize] is a sign on a door: "Staff only, show your badge."
