To use a YubiKey with LastPass you need to have a LastPass premium account.
Any YubiKey configured with a Yubico OTP works with LastPass (with the exception of the Security Key, which supports U2F only). A specially priced bundle with YubiKey + LastPass is available in the Yubico store.
The Yubico page on the LastPass site lists the benefits of using YubiKey to protect your LastPass account. For instructions on how to associate your YubiKey with your LastPass account, see YubiKey Authentication in the LastPass user manual.
The LastPass Mobile Device Application supports YubiKey two-factor authentication using the YubiKey NEO on Android devices. The YubiKey does not work with the LastPass Mobile Device Application on the iPad/iPhone due to hardware limitations on the Apple devices. For more information, see Introducing LastPass Mobile Support for the YubiKey NEO.
