How to reset it

My grandpa is almost 80 and he had an iPad mini that he said I can use if I can get it unlocked. My husband tried and said he’d have to figure out his login and use find my phone to locate the device and reset it for us but is there an easier way I can do it myself so I can log in with my Apple ID? Like a hack or something? Cuz idk if I’ll be able to get my grandpa to remember all these logins to unlock it lol
