I have a few family members that I help support. For instance, I installed Linux Mint on my grandmother’s PC. She doesn’t know any different and my young cousin doesn’t understand it so he finally stopped giving it viruses. I used to use TeamViewer to take over her PC when she needed support but I got my account banned because they believed I was using it commercially. Oh well!
I have Tailscale installed on the computers. This gives me SSH access. What would you suggest? RDP? Something else?
Alternatively, you could set rustdesk to run on startup/login, so neither you nor the user needs to manually start it.
