Mac owners with more than a touch of paranoia should head straight for the website of Moldovan security firm Rohos with any old USB flash drive at the ready.
On said site they'll find the oddly named Rohos Logon Key, which is a new (the OS X version at least) downloadable application that turns the USB drive into a key that can lock a Mac up tighter than Gordon Brown's wallet.
Stick it in
In operation, it's a simple matter of turning the computer on and inserting the drive at the logon screen.
After a few seconds the software kicks in and authenticates the key using a unique serial number attached to the USB hardware. In other words, it saves you the two seconds it takes to type in a password.
Windows too
Rohos says that its software doesn't actually store anything on the flash drive, as all the software does is look for the particular key associated with its lock. That means the drive can be used as normal, even if it's formatted for Windows or Linux.
Rohos Logon Key costs $29 (£15) and yes, there's a Windows version too. Just don't go losing that precious dongle, ok?
