Secure .NET secrets management uses user secrets for local development and environment variables for production to keep sensitive data outside your repository. This prevents accidental exposure and ensures compliance.

The best way to store local development secrets in .NET is using the dotnet user-secrets tool. It keeps sensitive configuration data like database connection strings safely outside your project directory and source control.

Yes, you can bind environment variables to strongly-typed options classes in .NET using IConfiguration and the Options pattern. This secure configuration binding also supports validation to ensure environment-injected secrets are correctly formatted.

Storing passwords in appsettings.json is a security anti-pattern because it commits sensitive configuration data directly to your source repository. You should use user secrets or environment variables instead to prevent accidental exposure.

Yes, .NET supports zero-downtime secret rotation by providing specific patterns for updating sensitive configuration data without restarting your application. It also recommends integrating managed identity to eliminate secrets entirely in cloud environments.
