Can't register my YubiKey

I have some trouble to register my YubiKey with Lastpass.

I go to my settings and click Multifactor options. I then click the edit button to enter the settings of my Yubico YubiKey. I switch Enabled to Yes and push on the YubiKey after i clicked on the field of YubiKey #1. My password gets filled in and then i push Update. Then i get the following error:

An error occurred.
At least one of the YubiKey tokens provided had an incorrect length.


Any help?

I have this fixed....wanted to do it with static password, but it needed to be OTP

I am getting this message An error occurred.
At least one of the YubiKey tokens provided had an incorrect length but I don't understand how to correct it. I found a post that refers to OTP, but again, I'm not sure of the significance - do you have any suggestions?

Thanks!

I see the same error. I have a YubiKey 4 which is listed as supported.

Make sure the YubiKey is configured not to use U2F:

Yep, I also have this issue and support was unwilling up until now to help. This with a “premium subscription”’ I’m very disappointed at the moment. I wonder if another password manager works or is it just a last pass issue.
Good luck!

Confirmed that this is STILL an issue in mid 2019. My yubikey is and older black one, so it's not the U2F issue. If they don't support certain yubikeys, the should give you info in the UI about how to tell if a particular yubikey will work.

Hi,

Can you please confirm which Operating system and device you are experiencing this issue on?
