Apple's privacy-focused consumer branding has been bolstered with a new login service which will restrict advertiser's access to consumer data.
Sign in with Apple will let users quickly sign into apps and websites and will be introduced in iOS 13.
The move was announced at this year's Worldwide Developer Conference (WWDC) in California, alongside the end of iTunes and a $999 computer stand.
The service is a direct challenge to Google and Facebook's advertising model which links users' account sign-ins to an Apple ID instead of a Facebook or Google account.
Google and Facebook's account login systems are used by many online services, from The New York Times to Spotify and Airbnb, as an alternative way to access users' accounts.
The systems have been criticised for allowing tracking between websites and allowing advertisers to build up detailed profiles of users' web habits.
"Apple does not use Sign In with Apple to profile users or their activity in apps," the company stated explicitly.
