Allgemeines Diskussions-Forum » master password

since i seem to be having a lot of trouble with security, i had a thought. is it possible to make up a usb drive with an extremely difficult password on it, and use that (the usb drive as the master password) in my computers?

I didn't find the right solution from the internet.
