share documents with stakeholders

Hi Community,  I just finshed a magazine layout on adobe indesign.  My next step i wanted feedback from the stakeholders however I'm not sure how to go about it.  I do not know any of the stakeholders email address to do invite only therefore, I was reading about the public asccess with a passcode.  I'm posting this to find someone who knows how this work and what do I need to do. I read the tutorial but do not feel comfortable.  

Thank You
