[Cross-Device Authentication (CDA)](https://passkeys.dev/docs/reference/terms/#cross-device- authentication-cda) allows your iPhone to vouch for your logon attempt on your Desktop because it is cabled to it or within BlueTooth range. About the time the pandemic arrived in the US, almost all Credit Cards had these chips on them. The contactless nature of these credit cards meant germs were not spread as much. The chip stores a private key. Effectively, TPM hardware in your desktop or laptop or iPhone has one of these credit card chips. The public key can travel all over the internet, but the private key should never ever leave the device it was created on. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1989976 Title: [upstream] wishlist: Passkeys should be supported To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1989976/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
