activation lock for father who has passed away
Hi. My Father passed away and we are handling his affairs. He had an iPhone 6s, which I have restored to factory setting by connecting to my MacBook, but I need to get through the activation lock in order that I may use it as a new iPhone. The difficulty is I have my father's e-mail address but don't know his password and despite going through to the guidance on apple support I can't sort this out. Has anyone else found difficulties on this and can give me some simple guidance. Thanks,
iPhone 6s, iOS 14
