I just got the update on my phone on Google play, Firefox now supports 3rd party password managers for passkeys (on android 14+). Just tried it, and I got prompted with my 3rd party password manager, so it works!

    You delete it from your account, that makes it invalid. Just like removing an entry from authorized_keys. If the site does this after changing the password or not is up to them.

      I mean, suppose that i save a passkey in my password manager, then because of my bad opsec someone else gets hold of it - if I delete it from my account, the attacker still has a copy and I have no way to invalidate it

      I checked again on eBay, there’s no “list of passkeys” even if I created 4 of them (one for each browser on each of my computer + one synced via password manager)

        eBay has implemented their passkey support poorly. “Turn off” will invalidate them. Most sites have a list of passkeys and you just delete the one you don’t want working anymore. At that point it doesn’t matter who has it, it’s useless.
