Github allows one to set a 2FA security key on login, via WebAuthn according to [the docs](https://docs.github.com/en/free-pro-team@latest/github/authenticating-to-github/configuring-two-factor-authentication#configuring-two-factor-authentication-using-a-security-key).
However this functionality does not work with OnlyKey;
OS: Windows 10 Education
Version: 10.0.19042 Build 19042
OnlyKey Firmware: Upgraded to v2.1.0 (the version on the “upgrade” page, retrieved today)
Here’s what happens:
1. Github identifies the key.
(At least it doesn’t launch any error messages that you get when you don’t have a key)
2. Windows prompts me to touch the key.
3. The OnlyKey LED flashes blue.
4. I push any button on the OnlyKey.
5. Github says: “This device cannot be recognized.”
I did enable 2FA for Github via SMS.
I am glad to provide more info.
Thanks in advance.

@Scorbie Have you been able to register any other FIDO2 security keys? We have not had any other reports of issues it may be a browser issue.

@t11
Oops, you were right; It didn’t work on Firefox but works on MS Edge.
(This was my first FIDO2 security key, by the way.)
@My1 In case of future reference:
Thank you all for the help!

okay that’s an interesting error to say the least. I think I need to try some stuff with this and dig a little because this really makes me curious.

Hello,
I have the same issue with FireFox. **However, its works fine with Edge**.
- **OnlyKey Firmware** : v2.1.0-prodc
- **OS** : Windows 10
- **Browser** : FireFox 87.0 (64 bits)
However, GitHub does not show any error message. The image below shows the error with FireFox 87.0 on Windows 10. _Please note that it works fine with Edge_.
Note: I tried using Ubuntu `20.10` with FireFox (version `87.0` - 64 bits) and Chrome (version `89.0.4389.114` - 64 bits). **The OnlyKey does not even blink blue** (thus, the operation fails).
Regards,
Denis

**UPDATE**
Hello,
I just used the OnlyKey under Windows 10 / FireFox 87.0… and it works.
However, the use case is different from what I mentioned earlier:
In my previous post, I mentioned that I could not set up the OnlyKey as a security key for GitHub.
Thus, I’ve set up the security key using Edge.
Rigth now I was logged on my GitHub account (using Firefox), and I deleted a repository. GitHub asked me for confirmation, and then asked me to touch my security key. I touched it, and it worked out OK.
Therefore the problem seems to happen only when you try to set “declare” the OnlyKey as a security key. But, once declared, it’s OK.
Regards,
Denis
