ASP.NET Core Identity uses default values for  password policy settings, in this article we shall see how to override or customize Asp.net Core Identity's password policy ?

By default, Identity requires that passwords contain an

                 options.Password.RequireDigit = true;
                 options.Password.RequiredLength = 6;
                 options.Password.RequireNonAlphanumeric = false;
                 options.Password.RequireUppercase = false;
                 options.Password.RequireLowercase = false;
             });
