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.
Tell that to cops at traffic stops
Yes it’s a thing
Then you have a nice juicy lawsuit. No legal protection is going to prevent a rogue cop from getting your data. https://xkcd.com/538/
Good luck in court

Make sure your devices are up to date
You link to articles about law enforcement hacking phones to get data as a reason not to use biometrics? If they are hacking your device it doesn’t matter if you use a password or a fingerprint.
On the contrary, these tools only work when the phone has been unlocked since boot on any modern phone, so you can turn it off or reboot it
True. In the context of this thread it doesn’t matter though.
