How to set password on sys_user from script in a SCOPED APP?

[corbettbrasing1]

I know that when in global you use setDisplayValue() to set the password and that works fine, however in a scoped app setDisplayValue() is not an option.  

How do I do this?   setValue() does not work, nor does gr.password = "blah";//with an gr.update() after it.

So the answer I found out is you have to use GlideElement.

Setting display value in scoped apps.

So this works:

var gr = new GlideRecord("sys_user");
gr.get(some_sys_id);
gr.user_password.setDisplayValue("test");//useing glide Element
gr.update();

This does NOT WORK

var gr = new GlideRecord("sys_user");
gr.get(some_sys_id);
gr.setDisplayValue("user_password", "test");//useing glideRecord
gr.update();
