Support WebAuthn Passkeys

[era]

Firefox supports WebAuthn, but as far as I could tell only with hardware tokens. I could not find a word about Firefoxs support of Passkeys (like Apple announced recently) anywhere

Personally I don't know why passkeys werent adopted much sooner, it seems such a long hanging fruit to just store the key in the FF password manager.

I use FF to support a web where there is not only one option, like Chrome, but FF keeps falling behind and behind instead of being at the forefront. This should be a top priority.

With 115.0b3 I'm able to sign into https://passkeys-demo.appspot.com with a passkey created from Chrome (even if FF insists that "This device does not support passkeys...").

You mean via QR code that is shown by Firefox and the passkey was created by Chrome on Android?

No, passkey was created from chrome canary (and presumably windows 11, I had my yubikey 5 present but it seemed to use windows helo), then I could use it from Firefox dev.

Passkeys are really gaining momentum. Firefox is going to be left behind if this isn't implemented in a timely manner.

I'd hate to see the only real alternative to Chrome losing more market share by being perceived as less safe or harder to use.

It seems that Windows Hello soon also supports passkeys that are stored on the phone. Thus, passkeys could then also be used in Firefox and native apps.

GitHub.com now supports Passkeys. As someone who uses Firefox Developer Edition, it is disappointing that I cannot use a feature that is supported on Chrome and other browsers on the biggest Git platform.

I agree that it would be great if Firefox added Passkeys.

This is weird, I could login with my yubikey as passkey. The login form even says, you browser does not support passkeys. But I can just click the "login with passkey" and it just works. The passkey was generated with Chrome though. Is the initial encryption challenge the remaining part for firefox?

Added key in chrome for github. I could login with it in Firefox. Is the initial encryption the only remaining part for Firefox to implement?

It's weird though, the login form even says that my browser is *not* supported, yet it works fine.

@eraFirefox was slow but sure if you ask me. I am starting to feel like they played it slow in other to leverage the built-in OS flows when they were available.
According to this post here https://blogs.windows.com/windows-insider/2023/06/22/announcing-windows-11-insider-preview-build-234... Windows is going to natively support the FIDO2 Authenticator Selection Dialogue that we have seen Chrome, Edge & Other Chromium based Browsers support on their own for quite sometime now. The good part is that it comes with pairing with another device via Qr Code scanning. And Persistent Linking as well to skip scanning the Qr Code again and again if you have used it before. Chrome & the likes who developed their own built-in mechanism are now removing them in other to rely on the one provided by Windows. I cannot speak for Mac OS but I wanted to share that for Windows here if it will be useful in anyway.
