Limiting access to content


I need to limit access to a certain content on the website that I'm developing with Elgg. I know there is a default access permitions, but it is not what I'm looking for this case.
What I wanted was that only the creator could access the content, but then could give access to certain people. The contents could be protected by a password or something,  and then the creator could share the password with the users he wanted. This is possible?

This is just my idea ​​how to limit access to this content,  if there another way or if someone has another idea of how to make this possible I am grateful to hear.

Thank you
