Q: I am trying to get videos my daughter did from her iPad.  She died of cancer and she had iCloud. I am not smart with a computer she always did stuff for me

Do you know the relevant Apple ID and password? Do you have physical access to her iPad?

Tonefox asked the right question.  I just wanted to let you know how very sorry I am for your loss.  It must be very difficult especially at this time of the year.
