Your iPhone Is Probably the Center of Your Digital Life
So your iPhone has a lot of personal and sensitive information stored on it. That’s reason enough to use a stronger passcode. But when you realize just how much of your digital life centers around your smartphone and the phone number associated with it, the stakes get even higher.
First off, your iPhone is likely logged into most of your social media and email accounts, which could let an attacker access pretty much the entirety of your online life. Most users receive two-factor authentication codes on their smartphones, meaning that a hacker could compromise your SMS one-time passcodes or your Apple 2FA codes if they had access to your phone.
