iPhone Security Buff: iOS 26.4 to Shield Every User Automatically

The upcoming iOS 26.4 update introduces a significant shift in iPhone security by enabling Stolen Device Protection by default for all users. Previously an opt-in feature, this security layer requires biometric authentication for sensitive actions like changing Apple ID passwords or accessing saved credentials, bypassing simple passcode entry. By automating this defense, Apple aims to neutralize the threat of thieves who observe a user's passcode before stealing the device, ensuring that even if a phone is snatched, the most critical personal data remains locked behind biometric verification.
