How can I make my own USB login key?

What do you mean by “login key”? Are you trying to make a USB drive that automatically logs you in when you insert it into a USB port? That’s definitely possible but will probably require some programming knowledge.

@cam yeah. There is Rohos, but that’s kindif expensive, but I found a Vbs script to send keystrokes, who knows.

I would look for a way to turn your USB stick into a CD drive – that way, you can use a CDs autorun functionality to run a script that will log you in. I never got that to work when I was looking around, but you never know… years have passed and someone may have figured it out.

You just need a special software. For example i’m using ProteMac LogonKey. It’s like a Pohos but chepear) http://www.protemac.com/logonkey/
