I think that biometrics would be somewhat challenged, from a legislative barrier perspective, on the email front. There are no commercial bank initiatives around digital ID and authentication that rely on biometrics, to my knowledge, not in Canada for sure, but even—I'm trying to think—globally.
The one example of biometrics being used in digital ID that I can think of is the project currently being developed in Ontario in support of the Ontario effort towards digital ID, which I believe is called eID-Me. It was done in partnership with a financial technology company and would have your identifier, for Ontario government purposes only, on your phone. It would be password linked and biometric—either thumbprint or facial recognition. Globally and in Canada, it would be, I'd say, the major one that attempts to go the biometrics route rather than the bank log-in credentials route..
