When I picked the options for my laptop, I made sure I included a fingerprint sensor. I like being able to log on to my laptop using my fingerprint. It's faster than typing, and I don't have to flip it out of tablet mode. I'm glad that the LastPass password manager can use a fingerprint to authenticate, too. Neat!
Here's how I tweaked my fingerprint scanning to fit the way I like to work even more. First, I opened the Lenovo - Fingerprint Reader settings in my Windows Control Panel. I unchecked Use fingerprint scan instead of power-on button. I don't mind pressing the power button, and I think this will save a trickle of power.
Then I clicked on More settings and unchecked Enable indicator lights on sensor. This turned off the green LED that had previously been a little distracting. The fewer bright things I have in my field of vision, the better. Tada!
I think it's incredible that I can authenticate using a fingerprint. I know it's been around for a while, but it's still amazing to think of how the algorithm might work. Hooray for all the geeks who worked on making this possible.
