Everything you need to know about iPhone iOS update 16.3

Apple has started rolling out the latest iOS update to users with iPhone 8 and later. iOS and iPadOS 16.3 is loaded with a slew of updated features and tweaks, which we’ll take a look at below:

Security Key

According to Cnet, iOS The biggest update that comes with the 16.3 update is the addition of Security Keys, a fairly modern new passwordless authentication technology that's been gaining a lot of traction lately. Cnet reports that the iOS version of the security key will not replace a user's password, but will instead enhance user security in the form of two-factor authentication. The security key was first developed by the FIDO Alliance, a multilateral partnership made up of some of the tech giants including Apple. The new iOS implementation of security keys only works with FIDO Alliance certified security keys.

SOS UPDATE

Apple has been trying to grab everyone’s attention lately by implementing satellite communications technology in the latest generation of iPhones. SOS on iPhone 14s can call emergency services by pinging satellites in the sky, even if you're not within range. The new update aims to reveal inadvertent calls by requiring users to hold down the side button and volume buttons simultaneously to start a countdown. Then, once the countdown is over and the user releases the button, it makes an emergency call for them.

Other Updates

In addition to these updates, there are several other updates and tweaks included in iOS 16.3, including updated wallpapers to celebrate Black History Month and improvements to the second-generation Apple HomePod New support.

In addition to the feature updates, another key aspect of the update is the enablement of Hardened Runtime, which helps prevent unauthorized access to sensitive user data. Additionally, the update includes improved state management, addressing memory corruption, logic errors, and privacy issues. The kernel has also been updated with better memory handling to prevent arbitrary code execution with kernel privileges, further enhancing security. Additionally, Safari has been updated to improve cache handling to prevent potential denial of service attacks. Finally, the Screen Time feature has been updated with improved privacy data editing to ensure sensitive information is protected and prevented from being leaked.
