# Configure Identity
ASP.NET Core Identity has some default behaviors that you can override easily in your application's startup class.

By default, Identity requires that passwords contain an uppercase character, lowercase character, and digits. There are also some other restrictions. If you want to simplify password restrictions, you can do that in the startup class of your application.
