The Information reports that Apple's time-saving Sign In with Apple feature is under investigation by the US Department of Justice as part of an antitrust probe.

The authentication tool allows users to log in to websites and apps with a single click using their Apple ID instead of entering their email address and password. Apple also touts the "privacy protection" benefits of this system. However, the report claims to be investigating whether signing in with Apple makes it more difficult for iPhone users to switch to other platforms.

How did this happen?

The issue stems from Apple's insistence that apps offering third-party sign-in options from Google, Facebook, and other services also include a Sign In with Apple option. The difference is that the login buttons from Facebook, Google, LinkedIn, and others provide app developers with user information such as email addresses and profile data, while the Apple version does not.

Because of this, some app developers have reportedly complained that they risk losing useful information about their customers; according to The Information, two iPhone app developers have removed all removed the sign-in button.

The Sign In with Apple button was introduced in June 2019, and Apple initially required app developers to display it above the sign-in options of competitors such as Google and Facebook. These placement guidelines were not a formal requirement and have since been dropped, which may be indicative of Apple's approach, which has not always worked well with developers.

Just last week, email app maker Blix refiled its private antitrust lawsuit against Apple, saying the button requirement was unfair and an example of what it called "coercion."

In its lawsuit, Blix said Apple could use the sign-in button to retaliate against problematic developers. Last year, when Fortnite maker Epic Games refused to comply with Apple's rules regarding the use of the iOS in-app purchase system, Epic tweeted that Apple would remove the "Sign In with Apple" button from the game. Epic later stated that Apple backed down from its threat.

Apple claimed that it created guidelines for the feature based on developer feedback and said it does not require apps to offer third-party sign-ins.

What does that mean for you?

At this time, it will have no impact on iOS 14 users. The investigation may not continue, and if it does eventually go to court, it may be ruled in Apple's favor.

If a verdict is rendered against Apple, it could result in a fine, but as one of the wealthiest companies in the world, Apple probably does not care.

Of course, Apple could be told that it can no longer require developers to include the Sign In with Apple feature along with other third-party logins. While this may be good news for some developers, it will definitely reduce consumer choice. Not everyone has a Facebook or Google account, but if you are using an iPhone 12, you definitely have an Apple ID.

On the other hand, if the ruling is in Apple's favor, more app makers may respond by removing the Quick Login button altogether.

No one wants to go back to the bad old days of having to type in passwords all the time. Still, if that eventually happens, at least we can be sure we are using the best password manager.
