Restict access through web interface

so since the wd mycloud desktop app is no longer working and not supported anymore ( for whatever stupid reason ) users of my cloud have to login through the web interface ( ) and use their email / password. but is there a way to control the access the users have to specific pc’s. atm they can login from anywhere and i only want them to have access to the files while in the workplace, and this would stop them from sharing their info with other people.

with the desktop app i was able to send them a code which would let them access it from a single device or they would need another code to access it on other machines. but since the desktop app is discontinued how do i setup the web interface to be the same ?


p.s if there is a way to get the desktop app to work it would be even better!
