Passkeys support is now planned for Firefox 122.

This version was supposed to bring WebAuthn passkeys support as this source mentioned: https://connect.mozilla.org/...
Sadly this is not part of the release notes. I’m disappointed but I hope this will be implemented soon in Firefox.

It could be interesting to check for duplicates created from Kbin accounts.

What about F-Droid?
