Allowing public access to CRM Database

Allowing public access to CRM Database

I need to be able to allow password protected access to individuals without creating a ZOHO user account. We only need 3-4 user accounts (my board of directors), but I need the rest of my organization, about 25 members, to have read only access to our database that would include accounts, leads, reports, partnerships, contacts, events etc WITHOUT having to create a user account. Ideally, the members shall be able to enter a link that has a password prompt or landing page, and then opens up to modules that I would choose to be on this access page. Is this possible? If not possible through CRM is there another app or add-on that will allow this? This is most important for my organization to function. Thanks!
