-This document explains how to manage sensitive data for an ASP.NET Core app on a development machine. Never store passwords or other sensitive data in source code. Production secrets shouldn't be used for development or test. Secrets shouldn't be deployed with the app. Instead, production secrets should be accessed through a controlled means like environment variables or Azure Key Vault. You can store and protect Azure test and production secrets with the [Azure Key Vault configuration provider](xref:security/key-vault-configuration).
