I’m using Firefox as my main browser and see a lot of websites which support passkeys but only with Safari and Chrome, but not Firefox.
Why is that? Is this because of the market share or the implementation?
Looks like Firefox has some different implementation ways than the other two, according to AuthGear https://www.authgear.com/post/passkeys-compatibility
I’ve had them working on Firefox using series 5 Yubikeys and using KeePassXC + KeePassXC-Browser extension. These were on MacOS, though I’m not sure that matters.
The current Yubikey firmware can store 100 passkeys. Mine is older and can only hold 25. The firmware can’t be updated. https://www.yubico.com/resource/whats-new-in-yubikey-5-7/
