Pioneering authentication standards for the modern web

Built for security

Mobile authentication software or SMS could not stop phishing and man-in-the middle attacks at Google.

Employees & customers

The search giant made YubiKey mandatory for all employees, and optional for all end-users.


Zero account takeovers. 4x faster to login. 92% fewer support calls. 100% acceptance rate.

Authentication without compromise

Historically, there has been a tradeoff between great security and usability.

Passwords are fundamentally broken. Basic two-factor authentication, like SMS and mobile apps, is increasingly vulnerable to attackers. And the more secure hardware technologies, such as traditional smart cards, are difficult to deploy and use at scale.

The YubiKey changes this.

Easy to use across all devices

Register your YubiKey

To use the YubiKey, go to the Security Settings of a supported service and and select “Add Security Key”.

Insert YubiKey & touch

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 YubiKey to device

Tap the YubiKey on NFC enabled devices. Once registered, many services will not require the key after first login – it just works!

One key to access them all

The YubiKey works with hundreds of enterprise, developer and consumer applications, out-of-the-box and with no client software.

To protect access to both legacy and modern IT systems, Yubico pioneered new innovative security protocols and added them all to the YubiKey.

Inspired by the word ubiquity, one single YubiKey can authenticate to hundreds of leading global business and consumer applications.
