That's a great question because it's something that we face in the government all the time. It really comes down to accessibility. Does every Canadian have the technology necessary to access using facial recognition?
It's not foolproof. It is one factor. We always say there are three factors. First is something you know, and a password is something that you know. Second is something you are, which would be facial recognition; a fingerprint is another example. Then third is something you have.
I always think, when I walk into the building at the CSE, that something I know is my PIN code to get in. Something I have is my badge, and something I am is my photo and my face that our security guards check as I pass through the different gates. Those are the physical-world examples of what's there.
Yes, that would add another factor. Passwords would be something you know. Something you have are things like hardware tokens, but those, again, are about accessibility. It really is about finding that balance, but it does add a factor of authentication and something that's important—
