At WWDC, Apple just announced Passkeys, their implementation of the FIDO protocols that aim to replace passwords. In Apple’s case, this capability will be available with iOS 16 and macOS Ventura, probably this fall. The other vendors are doubtless planning similar releases in a similar timeline.
Dan Moren from Six Colors has a post that gives a nice explanation of Passkeys and its operation by endusers. If you’re an Apple user with some or all of your passwords stored in the Apple iCloud Keychain, nothing much will change: you’ll authenticate with a fingerprint or face ID and a cryptographic exchange takes place between your device and the remote site to verify you. You can even use one device to log into another. Take a look at Moren’s post for the details.
What I want Apple to do to enhance this is to extend this and other privacy efforts backwards so older Macs and other devices can take advantage.
For example, I have a 2012 Mac Mini that doesn’t support Apple Pay natively. I can use my more modern iOS devices to approve purchases made on that machine. But it doesn’t support Hide My Email or other privacy mechanisms.
Get on this, Apple!
