How a YubiKey works
The YubiKey is a FIDO2- and WebAuthn-compliant multifactor authentication (MFA) hardware security key. Like advanced authentication methods like biometric MFA, a YubiKey protects you by giving you a physical key you must insert into your device’s USB port to authenticate yourself. Users with NFC-enabled phones can even use a YubiKey for their smartphone: just tap the YubiKey against the phone to complete authentication.
Where can you use a YubiKey
The YubiKey 5 series, the latest, strongest version of YubiKey, comes in various formats, including . The most preferred of the series is the YubiKey 5 NFC (near field communication), which is available for connection with USB-A, USB-C, Lightning, and NFC-supported hardware. The YubiKey 5 FIPS (Federal Information Processing Standards) is also available for government and regulated organizations that must meet strict security protocols.
Best of all, a YubiKey can be used in tandem with other cybersecurity solutions, including a LastPass password manager.
The Yubikey as multifactor authenticator
LastPass users can enable the YubiKey as a two-factor authentication device to access their vaults, by plugging the key into a device’s USB outlet or using its NFC capabilities.
A YubiKey works seamlessly with LastPass Premium, Families, Teams, and Business plans. It is also available on all major browsers and across multiple platforms (iOS and Android) with the LastPass mobile app.

Passwordless desktop vault access with a YubiKey
Users can enable passwordless login to their password vault by using a YubiKey 5 series hardware key, all thanks to its FIDO2-certified software.
The process is simple, too. All you need to do is enable passwordless login – for each trusted device – within your account settings. From there, the next time you need to access your vault, you’ll be prompted to insert your registered YubiKey into your device to log in to your vault. With a YubiKey 5 NFC hardware key, you’ll be able to log in to your vault, free from passwords, whether on an Android smartphone, Windows desktop, or Apple device.
