title: Virtual Data Room service with anonymity login management
body: <p>Please can someone recommend a virtual data room service which allows to create user login based on non-real email?</p>
  
  <p>To be more clear this is a scenario:
  I created data room named '123 5th Avenue' and want to set up log-in on this folder which will be distributed to many people. Instead of sharing this folder to the real emails of the people who need access to the folder, I prefer to create just one login/user like this: 5thAve@mydomain.com with appropriate folder permissions and distribute it to those ones who need it.</p>
  
  <p>I know that ShareFile by Citrix allows this but it is too expensive for me. It's welcomed if someone can suggest any service based on own knowledge or experience.</p>
  
  <p>Thank you!</p>
