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?

The firmware is indeed closed-source, so it's hard to audit. But they're popular, and a security flaw wouldn't go unnoticed for long.

There are other vendors such as NitroKey offers an alternative that offers both open source and audited hardware and software.

Thank you. I will look into it.

I personally went with a yubikey because their form factor is pretty slick. I'm not to worried about damaging 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.

[–] compostgoblin@slrpnk.net 1 points 15 hours ago

Haha well I feel less concerned now

[–] Telorand@reddthat.com 3 points 1 day ago

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.

I mean it's very complex and very expensive for "just" a key but if you want something fully auditable maybe Precursor.dev is a good fit. It's more than a key but the point is that it's as open as it can be. Honestly I'd consider it more a learning adventure that an tool at this point but still, see https://www.bunniestudios.com/blog/2022/towards-a-more-open-secure-element-chip/ for the philosophy and https://github.com/betrusted-io/xous-core with Vault for the key aspect specifically.

Isn’t Yubico (at least in part) Swedish?

[–] FriedRice@lemmy.ml 1 points 1 day ago (1 children)

I thought so too, but it might only be manufactured there

[–] double_oh_walter@sh.itjust.works 2 points 23 hours ago* (last edited 23 hours ago)

The founder lady is (somewhat) Swedish and it was incubated at KTH Royal Institute of Technology. That’s what I gathered from Wikipedia anyhow.

I would imagine the keyes would be more expensive if manufactured there.

I been wanting a yubikey but the fact their not open source really kills it. Any alternatives that are still iron clad?

I found this a few months, I have yet to purchase and try it for myself.

[–] FriedRice@lemmy.ml 1 points 1 day ago

I have now looked into Nitrokey, and I'm convinced that I will get me one of these. I would use it to log in to my pc, which has Fedora 40.I do I understand it right, that i f I follow the steps in the following link, I can use it to log into my PC?
