Hi,

I had to regenerate my yubikey as it as been lock on replayed_otp (I hope I have not been compromised as I don't understand why...)
I am on linux and used ykpersonalize tool : ykpersonalize -1 -cKEY -ofixed=PUBLICIDENTITY
I didn't put any uid option so by default it generates "uid: 000000000000"
I put the same number on https://upload.yubico.com/ in internal identity to make it works.

I would like to know if there is any security implication doing this like this and understand better the uid/internal identity uses..
Many thanks for your reply

Please use the GUI tool for this purpose if you're not familiar with the command line. It will do everything for you, the right way

Thanks I already know how to do that in GUI but my objective it to avoid it and know how to do it through the CLI...
Any inputs welcomed
