The release of iOS 15.4 introduced a suite of new features for iPhone users. One new ability – the ability to customize which apps you can access from the lock screen – could pose a risk to your cybersecurity. When trying this new addition, be careful which apps you enable. Messages and the Wallet app, for example, are both features that are accessible when locked. If your phone falls into the wrong hands, these apps could be accessed by third parties without needing your passcode.
