    {
        return new IdentityError
        {
            Code = nameof(PasswordTooShort),
            Description = Resources.FormatPasswordTooShort(length)

}

To customise a specific message, create your own IdentityErrorDescriber implementation. Here's an example:

public class MyIdentityErrorDescriber : IdentityErrorDescriber
{

            Code = nameof(PasswordTooShort),
            Description = "Your description goes here."
        };
    }
}

To use this new implementation, add it to the DI container in Startup.ConfigureServices:

services.AddScoped();
