FIDO Universal 2nd Factor (U2F)—a rapidly growing open authentication standard, allows greater user account login security
U2F is built to protect against phishing and man-in-the-middle attacks, allowing one U2F authenticator to access any number of services without any shared secrets. Since U2F has native support in platforms and browsers, there’s no need for drivers or client software
In order to take advantage of the security improvements provided by U2F, you'll need to purchase a hardware key. You can purchase the U2F key of your choice from a range of vendors
2 standards were created to envision a world without passwords:
- YubiKey (dongle)
- UAF (fingerprint, like iPhone 6)
YubiKey is a dongle that users carry to authenticate themselves. Compliant with FIDO, supported by Google and many other software vendors who need strong authentication.
Questions with this tag should be about programmatically accessing the key and validating users, not about the device itself.
