New MacBook Air User

I bought a MacBook Air for my daughter who was a senior in high school in 03/2020. Unfortunately, my daughter was hit by a car and killed in 10/2020. I can login to her computer because I know her password. Is there a way I can assign her computer to me without getting rid of her account. I would still like to be able to login and see her notes, text messages, music, and pictures. We cannot use her iPhone because it was shattered during the accident.
