Short answer
If the main account in your app is set up through a third-party or social login, Apple requires an equivalent option from another login service that limits data to name and email, lets people keep their email private, and doesn’t collect app activity for ads without consent. The guideline names no service; it lists the features. Apps that only use their own email and password sign-in don’t need it.
What 4.8 asks for, and the fix
01
Social login with no equivalent option
“must also offer as an equivalent option another login service with the following features:” Apple, Guideline 4.8
Google, Facebook, X or LinkedIn sign-in for the main account triggers 4.8. Add another sign-in option that has the three features below, and show it as a real sign-in choice on the same screen.
02
The other option doesn’t have the three features
“the login service allows users to keep their email address private as part of setting up their account; and” Apple, Guideline 4.8
The second option has to limit data to the user’s name and email address, let people keep their email address private when they sign up, and not collect their activity in your app for advertising without consent. Check the option you add against all three.
03
When you don’t need another option
“Your app exclusively uses your company’s own account setup and sign-in systems.” Apple, Guideline 4.8
Apple lists exceptions, including apps that only use your company’s own account and sign-in system, and education, enterprise or business apps that require an existing school or work account. Apple lists others too, such as government ID systems. If one applies, say which one in your reply to App Review.
Checked against the vendor’s docs on : Apple: App Review Guidelines, 4.8 Login Services (last updated October 16, 2026); Apple: App Review (replying and appeals).
