Sign in with Apple security
Sign in with Apple is a privacy-friendly alternative to other single sign-on systems. It provides the convenience and efficiency of one-tap sign-in while giving the user more transparency and control over their personal information.
Sign in with Apple allows users to set up an account and sign in to apps and websites using the Apple Account they already have, and it gives them more control over their personal information. Apps can only ask for the user’s name and email address when setting up an account, and the user always has a choice: They can share their personal email address with an app or choose to keep their personal email private and use the new Apple private email relay service instead. This email relay service shares a unique, anonymised email address that forwards to the user’s personal address so they can still receive useful communication from the developer while maintaining a degree of privacy and control over their personal information.
Sign in with Apple is built for security. Every Sign in with Apple user is required to have two-factor authentication enabled for their Apple Account. Two-factor authentication helps secure not only the user’s Apple Account, but also the accounts they establish with their apps. Furthermore, Apple has developed and integrated a privacy-friendly anti-fraud signal into Sign in with Apple. This signal gives developers confidence that the new users they acquire are real people and not bots or scripted accounts.
