Same for my mother using ubuntu. She do not know her password (the login is automatic). In case of problem, I connect using ssh.

Most of admin tasks are apt-get update/upgrade, rmdir --ignore-fail-on-non-empty Bureau/* (because she creates empty directory on desktop). The command cupsenable DeskJet-3630-series allows to unstuck the printer without mouse access (I was on my phone with connectbot). I have changed the computer after 10 years. It was transparent for her.
