How to avoid reinserting USB stick...

One of the frequently asked question from ours users:
I haven't figured out if there's a way to leave the USB key plugged in, lock the workstation, then only use the USB key PIN code to unlock the workstation.
Can you please let me know whether this is possible? Or, do I always have to remove, then reinsert the USB flash drive in order to only enter the PIN code?

Yes, assuming that physical access to the workstation is secure, and You would like to be able to unlock the workstation by only typing in the simpler USB PIN code rather than the strong windows passphrase.

Here's how to do it:
  1. Lock your Windows by Win+L (or Ctrl+Alt+Del -> 'Lock Workstation' button - if you have Win2k).
  2. Then to unlock click on the "Desktop is Locked" string. Rohos will try to unlock Windows by USB key (and PIN code if it is).
Note: To use this trick you should first login via USB stick.

This works very simple and efficiently. No need to reinsert your USB stick every time.
