Securing User Credentials With the YubiKey 4

I’m a big fan of the YubiKey 4.

The YubiKey is a security device that originally outputted a 44-character “one time password” that could be decoded and mathematically verified and used as a second factor for authentication. Over the last few years, improvements to the devices mean that they can also perform other important functions, such as storing:

  • Identity, Signature, and Encryption Certificates
  • U2F data for websites (GitHub and GMail, among others, support this)
  • GPG Keys

If you’re looking to set this up on your own, read on to learn how this extra functionality helps your security game, and how you can configure services to use it. Read more “Securing User Credentials With the YubiKey 4”
