1Password has worked well for my 90-year-old mother. I disabled the "ask to save password" option. If she needs a new account on something - which doesn't happen very often - I just use Screen Sharing (we both have Macs) and set it up for her. I also have her 1Password account syncing to mine. Although I do still get support phone calls when there's a glitch, it's worked out very well on balance, compared to the amount of support she needed before with account setup and not using the same password everywhere.
