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.
I have MFA in addition to that pw, yes
That’s news to me. Which other mobile authentication is there besides pin, pattern, facial and fingerprint?
Most phones allow passwords, or at least longer length pin.
My 6 character alphanumeric pin is more secure than your four digit numeric
