A Windows Hello USB fingerprint reader can make the mundane task of logging in to your Windows PC an easy and convenient affair. If you want to save time, here are some of the best external fingerprint readers you can buy for your PC.

Arcanite USB Fingerprint Reader

Arcanite USB fingerprint reader - 8

Arcanite USB Fingerprint Reader

View Price

The Arcanite fingerprint reader is small, compact and resembles the dongles for wireless mouse or keyboard. It plugs into a USB-A port and protrudes slightly with the scanner on top. The sensor is positioned at the top of the reader, so it’ll work best only on vertically oriented USB ports.

Registering the device with Windows Hello allows you to store up to ten fingerprints. So, if multiple users access your PC, each can log in using their biometrics. While the Arcanite fingerprint reader works straight out of the box, you may have to download the device driver from Arcanite’s website if prompted.

What We Like

  • Small and tiny
  • Affordable
  • Stores up to 10 fingerprints

What We Don’t Like

TEC Mini Fingerprint Scanner

TEC fingerprint scanner - 9

TEC Mini Fingerprint Scanner

While Arcanite’s fingerprint reader should work fine for most people, it only unlocks your PC. TEC’s mini fingerprint, thanks to its proprietary software, goes one step ahead by allowing you to unlock locked files and folders.

The TEC fingerprint reader draws parallels to the one from Aracnite in the design department. It has a sensor on the top portion of the dongle for easy access. However, it has an ordinary build quality and may disintegrate after a few months. As such, we’d recommend against repeatedly plugging the dongle in and out of the USB port to extend the scanner’s life. On the upside, it’s affordable and won’t drain your pocket.

What We Like

  • Small and portable
  • Unlock files and folders
  • Affordable

What We Don’t Like

  • Poor build quality

Yoidesu Fingerprint Reader

Yoidesu USB fingerprint - 10

Yoidesu Fingerprint Reader

View Price

Yoidesu’s offering comes with a side-mounted scanner, unlike the fingerprint readers from Arcanite and TEC. This design makes it a better choice for those who use a laptop over a PC. You can leave it plugged into a USB port on the side and use it like a built-in scanner.

Above all, it has a better build quality, thanks to the metal construction. At the same time, the Yoidesu fingerprint reader has a larger footprint compared to the devices above. At the same time, you can register up to ten fingerprints. Moreover, the scanner boasts snappy unlocking speeds, so you should be able to unlock your laptop in the blink of an eye.

What We Like

  • Faster response time
  • Excellent build quality
  • Larger footprint
  • Stores up to 10 fingerprints

What We Don’t Like

  • N/A

Verifi P2000

Verifi P2000

The Verifi P2000 is also compatible with some popular apps and password managers. So, if you use LastPass or 1Password, you can access all your credentials using just your fingerprint.

What We Like

  • Reliable
  • Works with apps and password managers

What We Don’t Like

  • Works with older versions of Windows

Kensington VeriMark

Kensington Verimark - 12

Kensington VeriMark

View Price

Kensington is synonymous with security. So, if you’re looking for a reliable, secure solution for Windows Hello, the VeriMark fingerprint reader is the best option. In fact, it’s being deployed in U.S. Federal Government institutions and organizations, and has some of the best acceptance rates for a fingerprint reader.

That said, it doesn’t work on a plug-and-play basis with Windows 11. As such, you may need to download the drivers manually. But, if you can get past this step, we highly recommend VeriMark for professional users who want to keep their accounts secure.

What We Like

  • Reliable
  • Able performer
  • Practical design

What We Don’t Like

  • Expensive
  • Not plug-and-play

A fingerprint reader is arguably more secure while a webcam is more convenient since you just have to look into it. You can pick either of them depending on your preference.

A long and difficult password can be harder to crack and might just be safer than using a fingerprint reader. But most of the time, a fingerprint reader is good enough since it’s both secure and convenient.

You can use Windows Hello on Windows 10 and Windows 11 computers.
