- Sign in with Apple allows you to sign in to apps and websites while protecting your privacy.
- Some developers may ask for your name, which you can edit. They may also ask for your email, which you can provide directly or use an alias.
- Apple knows if you’ve enabled Sign in with Apple for an app or a website, but does not track what apps or websites you sign in to or when.
- When you first use Sign in with Apple to sign in to an app, Apple uses information about your account and experiences with Apple, along with information about your device and device usage patterns, to help prevent fraud.
Enabling Sign in with Apple
Sign in with Apple protects your privacy by allowing you to sign in to an app (or app clip) without having to provide the developer with information that personally identifies you. Sign in with Apple also allows you to sign in to a website without having to provide the developer with any additional information that personally identifies you beyond information used by your browser for normal web functions. Instead, when you use Sign in with Apple, Apple provides the app developer with a unique identifier, allowing you to keep your information private. This identifier is distinct for each app developer, to help prevent different developers from gathering and sharing information about you across apps. Developers can also let you use Sign in with Apple for existing accounts on their apps or websites. If a developer chooses to enable this, you can keep the account you have already but sign in to it using Sign in with Apple.
Because certain apps may have reason to collect more information about you — for example, to refer to your account by name or contact you by email — some developers may ask for your name or email address when you use Sign in with Apple. Your name will default to the name associated with your Apple ID, which you can edit before sharing with the developer. If the developer asks for an email address, you can choose to provide the developer with any of the email addresses associated with your Apple ID, or to hide your email address. If you choose to hide your email address from the developer, Apple will generate and provide the developer with a unique email address for them to use to communicate with you. Apple will forward email received at that address to an email address associated with your Apple ID; Apple deletes messages after delivery or after a short while if undeliverable. On iOS or iPadOS, you can change the email address to which mail is forwarded, or disable email forwarding, by going to Settings > [your name] > Name, Phone Numbers, Email. On Mac, go to System Preferences > Apple ID > Name, Phone, Email.
If you choose to enable Sign in with Apple for an app, that choice is linked to the Apple ID you use for iCloud, so that you can easily use Sign in with Apple for that app on all of your Apple devices.
For fraud prevention and security reasons, the first time you use Sign in with Apple with a new app, Apple will share a simple binary score with the developer to give them confidence that you are a real person. This score is derived from your recent Apple account activity along with abstracted information about your device and device usage patterns. Neither Apple nor the developer receives any specific information about how you use your device.
Using Sign in with Apple
Apple knows when you enable Sign in with Apple for an app or website so that we can help set up the sign-in. When you then use Sign in with Apple with an app on your iPhone, Apple does not see or retain a history of which apps you sign in to or when you use Sign in with Apple — that information stays on your device. When you use Sign in with Apple on Safari, Apple sees when you sign in to a website so that Apple can authenticate your sign in, but Apple does not retain a history of what websites you sign in to or when you use Sign in with Apple.
Managing Sign in with Apple
Apple works to protect Sign in with Apple with strong authentication — powered by Touch ID, Face ID, and strong passcode options.
Apple may receive anonymous and aggregate information about Sign in with Apple, including information about the use of Sign in with Apple. None of the collected information identifies you personally. Apple may use information that does not identify you to improve Apple products and services, for marketing, and for fraud prevention and security purposes. Apple will not attempt to reidentify any anonymous or aggregated Sign in with Apple data we receive.
Apple will use your information as required by law and for fraud prevention. By using Sign in with Apple, you agree and consent to Apple’s and its subsidiaries’ and agents’ transmission, collection, maintenance, processing, and use of your information as described above.
