I want to start doing my elderly Mum's tax return for her, online. She has always done it by paper before. I regularly log in online to my own government gateway etc. I always use the same Macbook. It remembers my passwords etc. How can I best go about creating an account for her but yet not saving her passwords so they get mixed up with mine? Would the problem be solved if I log out of my mac and create a guest account (still on my mac) and make the account from there?
I'd be very grateful if someone has a good idea of how to do this. I guess I could open her account in private browsing and manually input her password every time, but it seems an annoying way...
