I’d like to bring up the suggestion of SoloKeys again for Hardware Security Keys , which was on the GH Discuss forum before the move here to Discourse: I’d like to suggest SoloKeys for the MFA page as another option under the “Hardware Security Keys” section. SoloKey devices use open source softwa…

As @jans23 pointed out elsewhere, their latest keys aren’t FIDO Certified either. I hadn’t had a chance to look yet, but that’s a shame :frowning: I’ll mark as waiting again to see if that ever changes.

A note relating to build quality and availability , i had been looking into buying a Nitrokey as recommended on privacyguides website. But after some research into their support and forums i found that a lot of users are complaining about nfc not working on their 3A models with pixel and samsung pho…

Based on the responses to the first forum thread linked, it sounds like their support is replacing models with defective NFC.

Correct me if I’m wrong, but after taking a quick glance at their online store, it looks like they’re now available .

SoloKeys 2 started to be sold in summer of 2023 in its store - but at first the only options were the “Limited Edition” SoloKey 2 devices with glitter in the epoxy covering the microcontroller used ( USB-A and USB-C , the latter is now sold out). However, by fall 2023, the “normal” non-glitter SoloKe…

These do seem to be widely available again, but they’re kind of ridiculously expensive IMO… [image] Solo 2C+ NFC Security Key (Built with Trussed®) Solo 2C+ : NFC Security Key, Two-Factor Authentication, U2F and FIDO2 - USB-C, Built with Trussed® Secure your logins with two-factor au…

[image] Remove Nitrokey I think we should just recommend SoloKey as an open-source FIDO2 key. Open-source doesn’t matter that much in here because good keys need to have a secure element, which will always be proprietary. What matters is for the firmware to be upgradable, YubiKey’s non-upgrad…

I don’t agree this is an “absolute joke”. Adding options to update the firmware adds an attack factor that needs defence. The entire idea of the key is that it remains untouched and cannot be altered. It also is far cheaper to replace keys than the risk and security needed to fix firmware issues at …

[image] ph00lt0: Adding options to update the firmware adds an attack factor that needs defence Yep, that is the exact reason I got told by Yubico themselves.

[image] ph00lt0: Adding options to update the firmware adds an attack factor that needs defence. It does add a security risk but its also a matter of your threat model and convenience. If keys are for your grandma sure you don’t want her to bother about upgrades. But for example you are in a…

Ledger, Trezor, and probably other crypto wallets have upgradable firmware. It requires multi-signature keys, which are stored in different locations and could be stored in HSMs. These devices store loads of cryptocurrency and are the best target for criminals. Yubico’s excuse for not using the sam…

Hi, just wondering, the SoloKeys website https://solokeys.com/ states that their Solo 2 key is FIDO certified (L1). Does that make a change in this discussion?
