As I understand you want to use your phone as WiFi hotspot.
Please go in your phone
Settings > Network & Internet > Hotspot & tethering.
Portable hotspot on settings > Configure hotspot.
Where you can see your hotspot name and password or you can use default password and network name.
For more details please fallow this link.

It's under your WiFi settings on your phone, it's the password /key. You can change or deactivated this but I would recommend against deactivating.
