Can a yubikey misused to track or link to different account?

[Julie]

Hi. If I use the same yubikey for a old gmail account for example and other apps or website from more trustable company. Would it be be considered a risk ? If so, to what level ?

Thanks a lot for your help.

Question about Yubikey

Hi PrivacyGuides community, I’ve got a question please; if I use one Yubikey for several accounts, can the key link me to each of my accounts associated with it? Are Yubikeys traceable? Do accounts and Apps know my Yubikey? I mean, do the key comes with permanent and unique traceable iDs? Any ideas? Thank you
