Hi,
if you have access to MikroTik router then you can see or change hotspot password. If not then ask your administrator to change your password.
hehehehehhe,
go to your router IP then user
ex.
WAN ip = 192.168.88.1 (ether1)
LAN ip = 192.168.1.1 ( hotspot IP / ether2)
now try with http://192.168.88.1/user , from hotspot user who already login
