Every computer, keyboard and laptop should come with one these days. Whether it's built in, on a USB cable or available in some other way. Not just business ones.

They're bloody brilliant.

My new laptop has one and it means if I want I don't really have to type my password any more for a lot of things, especially logging in to and unlocking Windows.

It's a shame it's not currently supported under Linux but I assume support will come eventually.

It does depend on having some decent software to sort out browser and program logins and thankfully the software provided (DigitalPersona) isn't completely shit.

I want something that will lock and unlock via bluetooth. I've always got my phone on me at work, so if I go away from the laptop it should lose the bluetooth connection to the phone, which should cause it to lock. As and when I come back, the connection would be reestablished, and should in turn unlock the laptop.

Of course, that would probably also mean that my phone dies partway through the day due to lack of battery, but one problem at a time!

I'm not sure how to! :$

(it's windows 7, and too much has changed)

Cheers, Ant, found it!

Now to see if it gets set back to defaults on reboot!
