Dear Mr. Premack: Although I am 92, I have kept up with and use a computer regularly. My son has helped me to establish online banking accounts, credit card information, email, Facebook, pictures and a lot more. I’m enjoying it very much. Yesterday my son asked how I am keeping my passwords, and we started wondering if my son could legally access all my computer files if I become disabled. Do you have any suggestions? – J.K. Your situation would not have been a topic even fiv
