How to get a package from packageShare

Hi All,

I would like to practice different dialogs present in the tutorial https://docs.adobe.com/docs/en/cq/5-6-1/developing/widgets.html#Basic Dialogs 

But I am unable to get the package Using ExtJS Widgets(specified in this tutorial)  from package share .

When I try to use package share link , it is asking for credentials. I am not sure which credentials need to be provided there. I have tried with AEM credentials (admin).But login failed.

Could any one please help me how to get and install the package from package share.

Thank You.
