YubiKey 4 Nano

Two-factor authentication made easy

A YubiKey is a small USB device you use in combination with your username/password to prove your identity.

With a simple touch, YubiKeys protect access to computers, networks, and online services. Keep one on your keychain with your keys, and a second backup key in a safe place at home.

All-in-one configurable security key

Touch to trigger FIDO U2F, smart card (PIV), Yubico OTP, Code Signing, OpenPGP, OATH-TOTP, OATH-HOTP, and Challenge-Response.

Easier and safer than authenticator apps

No more reaching for your smartphone, or re-typing passcodes. Just plug in your YubiKey, tap, and it does the rest for you.

Works off-the-shelf with hundreds of services

Use it with Facebook, Gmail, GitHub, Dropbox, Dashlane, LastPass, Salesforce, Duo, Docker, Centrify, and more.
