Support was first offered in May, but now Google suggests it as the default choice.
Passkey is some sort of specific unique key to a device allowing to use a pin on a device instead of the password.
But which won't work on another device.
Now I don't know if that key can be stolen or not, or if it's really more secure or not, as people have really unsecure pins.
Until Google "kills" passkeys as a default for personal accounts? They probably won't. Google can't kill passkeys in general btw, it's an open standard not a Google thing.
Kinda. Given that nobody else supported it Google dropping it did sort of kill it. Passkeys are very different as they are already supported by Apple, Microsoft, and scads of smaller companies.
