I programmed my Yubikey with the personalization tool, how to re-program my Yubikey so the next OTP will work with the Yubico validation server again? |

In the personalization tool (1.1 or above), set the following: Eg. * ykKey = b17....4b546a9402094744562543ed5 This is a hex value. * ykUID = ykStaticID = b8a....7ccf2 This is a hex value. * ykFlagProperty->ykFLAG_STATIC_TICKET = FALSE This is to make sure the Yubikey to generate one-time password, not a static fixed password. * Resume other ykFLAG_* you have changed from the default Yubikey: If you didn't change them, leave them alone. * Click on ykProgram to program the Yubikey |

And to switch between OTP mode to static password mode, you can set the flag to True (static passwd) or False (one-time random password) ykFlagProperty->ykFLAG_STATIC_TICKET This flag only exists in the VB tool, not in the browser ActiveX. |

Is it also possible to recover the original key settings? I've messed the key up too and now want to recover it. Thanks in advance, Regards, Jeroen. |

Hi, Same request , i've bought 3 yubikey , when i run the first time the tools to see the default value , i don't think that the value will be updated on the key "directly" without a message to validate change. Now one off my key is "unasuable" , somebody can help us to reset to default value ? Whose value need to be set in the tools fields , step by step. Thanks a lot for your help to be able to use again this key. Best regards One idea , could you not create a "basic" tools or a tools with two level "Basic" where we can set the "static password" or "Otp" only and advanced mode for expert. In all case open a box with a warning message before apply the change. |

We should of course have posted an official configuration tool earlier and I feel sorry for everyone who have been struggling with the sample code out there. It was never intended to be used as tools but rather as plain-vanilla boilerplate code. But - we've working on it now and will release a polished tool very soon. Stay tuned !

A new Yubico Personalization tool (Beta) is now available for download. The new personalization tool can be downloaded from the following link: http://www.yubico.com/files/Setup_YubiKCom_1_3_14.msi We have also created a User Guide for configuring the Yubico Personalization tool and reprogramming the YubiKey. It can be downloaded from the link below: http://www.yubico.com/files/Yubico_Pers ... draft3.pdf We would appreciate if you can test the new personalization tool and provide your feedback. |
