Meet the YubiKey

The authentication challenge

Balancing security and usability has always been a challenge. Software authentication, including passwords, sms and mobile apps are all increasingly vulnerable to malware and hackers. And the more secure hardware authentication solutions are difficult to use and deploy. The YubiKey changes this.

Ubiquitous security

Yubico was founded to set new global authentication standards, allowing one security key to access computers, phones, networks, and online services with a simple touch.

We named our invention YubiKey— Your ubiquitous key.).

How the YubiKey works

Register your YubiKey

To use the YubiKey, go to the Security Settings of a supported service and select two-factor authentication.

Insert YubiKey & tap

On a computer, insert the YubiKey into a USB-port and touch the YubiKey to verify you are human and not a remote hacker.

Tap on phone

For NFC-enabled Android phones, just tap a YubiKey 5 NFC against the phone to complete authentication.
