People use Sign in with Apple for its privacy and convenience. Although some apps or websites may require additional information — such as a date of birth or a region of residence — it’s essential to minimize your requests for data as people set up an account. Build on the trust that people have in Sign in with Apple by describing why you need additional data and clearly displaying the data you receive.
Collecting additional data
Sometimes, you need additional information to meet legal requirements; other times, you want additional information so that you can enhance people’s experience in your app. Be candid about whether additional information is required or optional, and avoid delaying or prolonging the Sign in with Apple experience.
As soon as Sign in with Apple completes, welcome people to their new account. Help people use their new account right away; don’t delay the experience by asking for information that isn’t required.
Clarify whether additional data is required or just recommended. If the data is legally or contractually required — such as an agreement to terms of service, country or region of residence, birth date, or information required by a region’s real-identity laws — make sure people understand that they must supply the additional information to complete the setup of their account. If additional data isn’t required, but can improve the user experience, make sure people know the request is optional and help them understand the benefits of providing the information.
Don’t ask people to supply a password. A key benefit of Sign in with Apple is that people don’t have to create and memorize additional passwords. Unless people have stopped using Sign in with Apple, don’t ask for a password.
Avoid asking for a personal email address when people supply a private relay address. Using Sign in with Apple, people can choose to share a private relay address that automatically forwards messages to their verified personal email account. It’s essential to respect this choice and avoid overriding it by asking for a personal email address. If you present customer service, retail, or other experiences that request identification via email address, you can:
- Make sure that people can view their private relay address in your app or website
- Direct people to Settings > Apple ID > Password & Security > Apps using Apple ID to retrieve their private relay address
- Use other identifying values, like an order number or phone number collected as part of a purchase
Give people a chance to engage with your app before asking for optional data. As people use your app, you can help them discover places where they can benefit from sharing more information with you. For example, you might suggest that they provide a contact phone number if they want real-time text updates or social network information if they want to play games with friends. If people choose not to provide optional information, don’t prevent them from accessing their account or using all the features of your app.
Displaying collected data
When people use Sign in with Apple, they may provide a name and email address. If people share this information with you, it’s important to display it in your app.
Be transparent about the data you collect. People value knowing how you use the data that they share with you. One way you can be transparent is to welcome people by using the name or email address they shared. Doing this helps establish how you use this information and, for a relay address, shows people where to find it in the future. If you don’t display all the data that people provide, they are likely to wonder why you asked for it.
