You need to set your YubiKey configuration to OTP authentication mode:

http://www.yubico.com/products/services ... bikey-otp/

Once that is done, visit the following URL: https://lastpass.com/debug.php and where it says 'YubiKey with LastPass', run the authenticator to make sure everything is working properly.

If no issues found, try to setup the YubiKey once again:

Let me know how it goes.

Best,

Hi all,
I had this error message, and it happened because I got a new YubiKey that I was trying to add to Lastpass, but when I was playing around with the Manager program I overwrote my factory set OTP settings with my own. Then that key would not work with Lastpass anymore because my new settings could not be validated. You need to re-upload the OTP information for your key to the Yubikey servers so they can validate it with other services.

BE CAREFUL HERE: I had to write over my Slot 1 config again to find my Public identity, Private identity, Secret Key. When you do this all the services you use OTP with already (Google, etc) will need to reset with the key, so make sure you have another way to login to them. For me this was a brand new key so I was not worried about overwriting that info again because it was not linked to any sites.

Once you find all that info you upload it to https://upload.yubico.com/ and so Yubico knows about your key again.

Once I uploaded my info to the Yubico server then Lastpass validated that key and let me save it.

Hope this helps,

I came across this thread via Google search. It helped me figure out my problem but with a different outcome:
LastPass requires a Yubikey that can handle OTP authentication. I had simply purchased a version that couldn't. So it's obvious that it couldn't work with LastPass. Now that I know that... (In my defence: I didn't act as clueless as this may sound. I will spare you the details.)
If you are in doubt which interfaces your Yubikey can handle, go to the Yubico homepage and download the "YubiKey Manager" tool.
If you consider buying a Yubikey, be very carful to check out the specs and compare pictures with the Yubico homepage.
Hope this helps.
