Regardless of how strong a password is, or what level of code-based authentication a website is using, any system that sends codes in a text messageΒ can be hackedΒ by a skilled hacker. The most secure way to set upΒ two-factor authenticationΒ is to use a reliable app on a smartphone to generate those six-digit codes or to carry a piece of hardware that can verify userβs true identity.
A device like theΒ YubiKeyΒ is just that sort of security enhancing hardware. These little key-shaped fobs plug into userβs computer and along with the password, complete the second half of aΒ 2FA web login. A hacker might find a way to lay his hands on oneβs passwords or intercept a six-digit 2FA code while itβs being sent to the phone, but theyβll have a hard time to snatch an actual key off userβs keychain. A YubiKey will directly provide another and more convenient method of authentication.
The YubiKey is like other, similar devices having a small metal and plastic key about theΒ size of a USB stick. They plug into a computer, and some also can connect to the phone. It can be used in either place, along with the password to authenticate web logins. It can be thought of as a physical key that, instead of unlocking a door, unlocks userβs online life.
There are several manufacturers that make these types of keys, and they all basically work the same way. They fulfill an industry standard calledΒ Universal 2nd Factor,Β orΒ U2F. The standard combines hardware-based authentication with public key cryptography. This method of cryptography is extremely difficult to compromise. These U2F keys simplify the process of securely accessing online services like Google, Facebook, Dropbox, Windows, and Mac OS.
