Search for your serial number (as printed on the dongle) in the txt file downloadable at the above link (ignore/delete any obviously dodgy exe files that are downloaded at the same time). And then use the tools from



The entry ending in A relates to slot 1, while that ending in B relates to slot 2.



I discovered this via this page:



While this list allows the yubikeys to be unlocked and re-programmed, assuming yours is listed (and mine was) - it is not a leak of the stored keys in the device.



If you had funds at MtGox when it eventually died, then obviously you should think about whether you really want to re-program your yubikey - as at some level it allows you to to prove ownership of your account there.

If it is, this is evidence of gross negligence by the Mt. Gox trustee. It should be reported to the Tokyo District Court and the Tokyo police.



(sorry for bumping just found this thead with google and felt like clearing this up)



These leaked keys are not in any way a security breach for Mt. Gox. These keys can only be used to reprogram your yubikey.

You can see the unlockcode as the locksmiths tool to change your the key of your front door to make it fit to another lock. By doing that, the lock the key originally was for, cannot be opened anymore afterwards (unless there where more than 1 keys).

The access codes linked to above will only allow for the re-configuration of any Mt.Gox issued YubiKey, but cannot be used to extract the secrets stored on the YubiKeys themselves. Please note that if you overwrite the configuration of a Mt.Gox YubiKey, there is no way to restore it, and the YubiKey will no longer be able to verify your identity for any Mt.Gox services used with it previously.

I now have a working yubikey, thank you!



I did not have any balance at MtGox so I don't care about losing a potentional access to the restored MtGox (lol)
