Hello,
Confluence allows to restrict page view/edit access using Page Restrictions (which override space permissions). However, is it possible to grant view or edit permission for specific page without adding that user to space permission? I've a space which has several pages inside. The user should be able to read only 1 specific page in that space, other pages should be not accessible.
Of course one solution would be to grant user space read right and then manually go into every single page within space and restrict view access for some specific user, but I hope there is some alternative like: find your page - edit page permissions - select type of access (read/edit) and username. The user will have read access only to that specific page, while the rest of the space content will not be available for browsing.
