Personal Hotspot

My question is I seem to have lost the Password that originally came on the phone in the “HotSpot Password” section were it is to be entered so that when someone would like to connect to u all u have to do is show them that password and they can connect to ur HotSpot then on ur phone and for some reason cant seem to find the Original one so just wondering if by chance could get a call back from someone with that password thank you.
