Re: two-factor hardware keys no longer working in firefox

Thanks for reaching out, and apologies for the delayed response here, we wanted to make sure there was not any updates on this topic.

 

Can I ask if the security.webauth.u2f flag has been enabled in Firefox? You can find it by entering about:config into the browser's address bar. From there, you can search for security.webauth.u2f and make sure it's set to true. Once that has been set, you should be able to add a new security key.

 

If you have any issues with that however, it may be worth setting up in Google Chrome first to configure a new key, then you would be able to sign-in with Firefox.

 

Sorry, I didn't have a more definitive answer to provide here but we're limited in our ability to troubleshoot issues on your browser, especially while official support is still not something we're quite able to offer at this time. 

Thanks for being here, sharing, and keeping our community awesome!
Best,
AndreaG

Re: two-factor hardware keys no longer working in firefox

Hey Andrea,

 

thanks for that workaround. Do you have an ETA for re-adding Yubikey support for Firefox?

 

I have added the key with Chromium (Ubuntu) and there, only the Yubikey is being requested.

With Firefox, by default an SMS is sent even though I login with Yubikey.

 

It is annoying to get spammed with SMS I do not need.

This still is an issue. Can we get an ETA for resolution?

Can confirm that logging in works with Firefox, but I first have to setup the key in Chrome.

Sorry for the trouble you've all had here. We've recently pushed some changes that should have re-enabled the work-around you were using previously. So please do try signing in again as you had done prior to these last few days.

 

If you continue to encounter issues though, please do let us know!


 

I am still seeing an issue:

 

macOS 10.13.6

Firefox 66.0.3 (64-bit)

security.webauth.u2f === true

 

This browser doesn’t support the FIDO U2F standard yet. We recommend updating to the latest Google Chrome to start using security key devices.

Re: two-factor hardware keys no longer working in firefox

I'm on Firefox 67 and also seeing that GitHub is telling me to switch to Chrome. I checked that u2f (and WebAuthn) is enabled in the browser's about:config. Once I switched the user-agent to Chrome, I was able to successfully register my hardware token. Can you unblock Firefox (at least the latest versions) from being able to register/use tokens?

Couldn't connect using Firefox either!

I also checked security.webauth.u2f is at true.

I'm also still encountering this issue in Firefox 67.0 on Ubuntu 18.04.

I can confirm as well that it doesn't work with Firefox 67.0.4 on Ubuntu 19.04 as well as on Arch Linux.
