Don't use a password to login into my personal PC. Only my sever is PW protected.

No cash for a server yet. Though currently I run OpenVPN on a ASUS RT-AC66U and I can use my smartphone to boot my PC with Wake On Lan remotely through the VPN (otherwise you can't access the router or any of its functions). Then it boots the PC, logs in automatically (netplwiz) and then instantly locks it with a task initiated after logging in that does: "%windir%\System32\rundll32.exe user32.dll,LockWorkStation". And then I can do pretty much what I want (stream a movie for instance if I set it up) and then shutdown the PC again if I no longer need it. Though without the VPN you can't do jack sh**.
