I need a cheap way to share out our company manual pdf file. Is there some sort of way I could setup a free website or hosted solution that will force the user when they go to the site to enter in a username and password to access the site. I then want the company manual pdf to be viewable but not be allowed to be deleted or edited. We have a website but the people that host it are terrible at helping out with this. I can't figure out how to add a username and password to a tab on the website. Any cheap options to do this? How about a NAS on our network that users outside the network could access with username and password?
