Sign In with Apple is a private, convenient way for Apple customers to create accounts with apps and websites. But so far only a smaller number of developers have implemented it. Apple says that if apps include other single sign-on options like Facebook and Google, they have to include Sign In with Apple. April 2020 is the deadline and it can’t come soon enough.
