How to grant access to page, for a non accessible space

[gandalf]

Hi Everyone

I need to grant access to a page for a user that has no access to the space, but only to that page. The restrictions mechanism is not viable for this scenario. 

Is there a more simple way to this than restrictions?

You can't do this, it's not possible to ignore the space permissions arbitrarily.

You'll need to put the page in a space that is accessible by that user, and make sure that the page is not restricted away from them in the hierarchy.

There is a hierarchy to access permissions.  If you have one page I would suggest exporting it and emailing it to the user.  In order to make a single page visible you would have to make the space public and then lock down all other pages.  This seems like a lot of work and risk in order to have one page shared to an individual.
