I wanna make more of myaccounts in the internet secure with two factor. I don't know much about it, but found out about Fido 2 and so. The security key my webbrowser shows often is the one from Yubico (BTW, I would like to get one that works with Linux, with USB and for phone with NFC) I got concerned when I noticed that Yubico is from USA, (??) Because I think NSA and thibgs like five eyes and so. Is there actually a risk that the for example is made an backdoor in the key?

They're not entirely un-auditable, either. A security flaw was discovered in the Yubikey 5 in one of the IC modules from a supplier, and they patched all of their keys from that point forward.

Unfortunately, all the 5's from before May 2024 are unpatchable (by design to prevent thieves from having an easy way into the key), but any key purchased now should be fine.

Well shoot, I guess it’s time to get a new security key. Am I better off switching to a NitroKey?

The issue isn't a big deal for the average user. The vulnerability required them to first get your username and password, physically steal your Yubikey, spend half a day using $10-15k worth of electronics equipment to repeatedly authenticate over and over, they then could potentially make a clone of the key.

Haha well I feel less concerned now

That depends on your threat model. For most people, the attack is probably unlikely to affect them, but I would recommend reading about the flaw yourself. It's not hard to understand.

Also, this was not the fault of Yubico but a supplier, and instead of waiting for the supplier, Yubico patched the flaw themselves by providing a custom library.

Whether you should replace your current Yubikey 5 is up to you.
