Depends on how they have set it up but in the ideal it will have be individually linked to a user. Iv heard of cheep complex managers just setting each fob to the same internal id. Meaning you can’t deactivate a fob or track the users. If anything it would be the same as CCTV on the lobby and public spaces of a complex. I would doubt that you would need it to exit as most doors need to let you out without resistance. This is possibly a fight between security and privacy. The other residence in the complex are more concerned with unwanted entries.
Teams could have been a plugin on outlook. Now I need two apps to talk to everyone on work.
