Autologin to a specific page

Hi,

thanks for your plugin and hope I can use for what I need.

1. I have a “resources page” which I want to grant the access only to people registered via email marketing service (it means they are not user of my wordpress site).
In the email I send to confirm the registration I’d like to insert the link to the “resource page” with autologin, like for instance:

https://www.mywebsite/resourcespage/?autologin_code=ABC123

So that only people that receive the confirmation email can access the resources page for download.

I have created a subscriber user called “autologin” in oder to have the code. And I want to use this single code in all the confirmation mail I send.

Is this possible?

2. visibility of the “resource page” should set as private or password protected?

Thanks a lot.
