T-Mobile Hotspot who is logged on

Just talked to tech support and got zilch. Is there a way to see who is actually logged onto my hotspot (not phone). Was told to there is no way to find out who is logged in and to change my password and THEN change all my devices I use passwords. When I was on Verizon for work I could see who was logged onto my puck, so is there a way to see whose logged onto my T-Mobile hot spot?
