What you need to know about USB fingerprint readers

Hate typing passwords every time you log into a computer? If that describes you, it will be faster for you to use biometric login. And if your computer doesn't have one, you can use a USB fingerprint reader. This USB device is small, light and easy to carry. Being biometric, it provides an extra layer of security that ordinary passwords simply cannot provide.

To prove it, I can't help but think of an interesting episode of Cobra Kai , the recent successor to The Karate Kid franchise. (The 30-year rivalry between the two main characters is thrilling to watch.) In this scene, Robby, Johnny Lawrence's absent son, steals a client's laptop. All he has to do is impersonate a smug tech executive and ask for the password. After quietly retreating with the device, Robby's gang quickly sells it on eBay while the gullible shopper relaxes at a Starbucks.

Here are some other desirable features of these devices:

• 360 degree detection :you should be able to log in from any finger angle
• Support for ten fingerprint IDs :if you work with Windows Hello or other similar systems, you should be able to register all ten fingers.
• Compatible with Google, Facebook, Dropbox and Microsoft ID :With a good USB fingerprint device such as Kensington VeriMark, you can not only access your computer but also several online services. In fact, these devices can act as "tokens" to help you get rid of phone verification on Google.

To set up a USB fingerprint reader in Windows 7/8/10, you need to set up Windows Hello.

Who doesn't need a USB fingerprint reader?

If your computer has an in-display fingerprint reader, you don't need this gadget. You can check your device's compatibility online for all known brands of Windows 10. You can simply set up the built-in scanner with Windows Hello.

Macbook Pro and Air users also do not need these scanners as they have Touch ID access on their computers. In fact, despite recent advances in facial detection, Apple is still betting big on fingerprint access for their devices.

Device not registering?

One of the few issues with USB fingerprint devices is that they can sometimes fail to read the user correctly. This is certainly true for me, as I think some people experience this problem more often than others. With wet or greasy fingers, you may fail authentication more often.

However, the well-known brands mentioned here are very sensitive to finger touch. Windows Hello also lets you authenticate all ten fingers in case one fails.

In summary

USB fingerprint scanners have many advantages in shared network environments. If you think a camera or keylogger is tracking your movements, it's best to enable fingerprint access. You can lock your screen and rest assured that no one will be able to gain unauthorized access to your system.
