Hello, out of the box the Yubikey Neo is already has the slot 1 already provisioned and works perfectly with LASTPASS. My questions are the following?
* How can I do that and what kind of parameter do I need to provide to the utility to reprogram the slot 1 to make the key to work with LASTPASS? * Is the slot 1 protected or is it possible to reprogram it? Thanks & Regards, Marco - StockTrader |

* Is it advisable for security reason to reprogram it with a new master key instead of using it out of the box? * How can I do that and what kind of parameter do I need to provide to the utility to reprogram the slot 1 to make the key to work with LASTPASS? * Is the slot 1 protected or is it possible to reprogram it? 1) This is up to you. If you choose not to trust Yubico. I use factory keys also in my private life outside Yubico, I do not re-program them. 2) You need the Yubico Cross platoform personalization GUI available at https://developers.yubico.com/yubikey-p ... /Releases/ 3) No, it is not protected just a warning pop-up informing you of what you are doing.

Do I need to set additional parameters? Kind regards & Thanks Marco - StockTrader |

For Yubico OTP, you gain nothing by reprogramming it! To make it work, you have to send the full private AES key to yubico. And if oyu reprogram it you get a identity starting with vv instead cc and yubico reserves the right to delete them from their servers if they suspect you don't use a hardware yubikey to generate your OTP keys etc. If you want increased security, you can't use Yubico OTP |

Using the provided key on the Yubikey is potentially even more secure because the key is never sent over the internet (of course it is encrypted, but with all the recent TLS bugs, who knows how secure) But if yubico want to steal your secrets, there is no way for you to know they don't have a secret method to read all your self created secret keys from your Yubikey. Either you trust them, or you don't. If you don't trust them, don't use a Yubikey! Of course you can use OTP with your own server and not send the key to yubico. That's what I am doing. But then it is your responsibility to make sure the key is stored securely at that server. This is more secure if someone successfully attacks the Yubico OTP infrastructure. But then the Yubico OTP infrastructure is most likely many times more secure than any server you would use. There just is no perfect security! |
