- The U.S. Department of Justice is investigating app developer complaints related to Apple's (NASDAQ:AAPL) handling of a quick sign-in option for iPhone apps.
- An increasing number of apps allow users to sign up with information already stored with another source like Google, Facebook, or Apple.
- Apple is requiring apps that include any type of quick sign up options to include its "Sign in with Apple" option.
- Apple says the button is important for user privacy. The complaints say Apple is making it harder for users to switch to rival devices.
- In response to the rule, some apps have removed all quick sign-in options.
