Apple, Google, and Microsoft recently announced that they would all support a common passwordless sign-in standard. That’s cute, but of the three, only Microsoft has truly embraced passwordless sign-ins. Apple and Google have a lot more work to do. A lot more.
User authentication is, as Microsoft would say, a hard computer science problem. Platform makers like Apple, Google, and Microsoft need to supply sophisticated and secure means for signing into accounts that are backed by two-factor authentication (2FA) or similar verification techniques. And then users need to adopt those features on all of their devices. We’re only truly secure---or as secure as we can be---when both happen.
