Isn’t the idea that not everyone has access to your biometrics?
There’s honestly no need to make computers ask people for piss scans:
something you know
A password
something you have
Access to the password
something you are
The person who knows the password
A password can be cracked and is often very bad.
But that can be said of any of the other such called factors:
A yubikey can be stolen
A fingerprint can be scanned and distributed
So its not really an argument against passwords (or passkeys, or passwordless, or whatever marketing want to call them these days).
Most people just need to fear their passwords being cracked remotely. In masses.
If your threat model is being known, people stealing your stuff to login to your things, this is very high.
My yubikey can be stolen but good luck guessing my PIN in the 3 to 9 tries allowed before it self destructs.
luck? I have a $5* wrench.
* (Actually a $7 wrench. Inflation is murder around here.)
If you have me… you win. My technology however will never betray me.
