Sign In with Apple

17.Apple recently announced ‘Sign In with Apple’, a new alternative to signing in with Facebook, Google, Twitter and other social media networks, scheduled to roll out before the end of the year. ‘Sign In with Apple’ will let users sign in to apps and websites using their Apple ID, and will place an emphasis on user privacy. Apple CEO Tim Cook said:

We focus on the user, and the user wants the ability to go across numerous properties on the web without being under surveillance. We’re moving privacy protections forward.348

New app guidelines provided to developers suggest ‘Sign In with Apple’ will be a mandatory feature for all apps offering third party (non-email based) sign in. The feature also lets users create a randomly-generated email address to cloak their real email address from developers.349
