@SiteRelEnby @whitequark it's an Apple/Microsoft/Google joint effort to use device-bound (which usually means TPM / enclave-bound) asymmetric credentials as authenticator.

It's also a FIDO standard: fidoalliance.org/passkeys/

I don't think Google are pushing for it any more than the other implementers?

@SiteRelEnby @whitequark double checking the relevant standards: Google definitely contributed, but they're far from the only names on there, and they don't seem overrepresented either?

@delroth @SiteRelEnby (I am upset about Google as the browser vendor specifically. FIDO is fine, passkeys are fine technologically probably)

@whitequark @SiteRelEnby yeah... I suspect that Chrome insists on hardware backing or system level credentials management to store the passkeys, and Linux doesn't really have a working API for either.

Could DBUS to GNOME Keyring :P

@delroth there is a general API (org.freedesktop.secrets) that will work with both GNOME Keyring and KDE Wallet, but I’m not sure whether that supports storing passkeys.

@Raqbit @delroth @whitequark @SiteRelEnby

Linux doesn't have a first class authenticator API yeah. If you want to, you can buy a security key and get passkeys that don't sync. I wouldn't recommend that to most people since you have to do your own backup management but if you're a linux user maybe they're less of a footgun.

There's nothing stopping vendors from implementing their own passkey syncing solutions for linux (dashlane and 1password have implementations, maybe more out there?)

@whitequark @delroth Why the fuck don't sites just let me give them the public half of an ECDSA key? No need for random potentially-trojanised standards...
