That’s Jack lamenting the fact that Apple is late yet again to another party.
I’ve already signed up for a gazillion websites using Facebook, Google, Twitter, Amazon, et al. I don’t really want to sign up for anything else. Can I go back to each of those websites and register again but with Sign In With Apple instead? Probably; at least for some. But that becomes triple the effort and since I use 1Password for almost every login already– which also works with Touch ID and Face ID, I’m not likely to put out much additional effort.
