i can unlock the session by adding this command to kde settings xdotool type MYPASSWORD ; xdotool key Return but anyone can see my password on phone i want a secure way to unlock my pc
This is actually a great idea. I'd like to expand on that to not just unlocking the desktop, but authentication in general. For example, it could be used for unlocking KDE vaults or issuing commands as root. There's lots of potential for your idea beyond desktop unlocking.
