If you don't know the password, you can consult the front desk customer service staff. In addition, if you don't know the password, you can also try common software such as master key. However, this kind of software is surfing the Internet, not cracking passwords. The surfing software only obtains the wifi password shared by online users, and then automatically uses wifi to connect to the Internet. If the password setting of wifi hotspot is complicated and no one shares it, then you can't surf the Internet. The password of a wifi hotspot can only be asked by the owner of the wifi hotspot.
