There are many reasons you might put off updating your iPhone to the latest iOS. Maybe you're out of space, or you worry the new operating system will slow down an older device. In any case, iOS 18.2 is not an update to waffle over, as it fixes a critical security bug in the Passwords app.
Apple's iOS 18.2 Update Will Protect Your Phone From a Security Vulnerability
With iOS 18, Apple introduced the standalone Passwords app, a built-in manager for your login data. But after a security researcher found a vulnerability in the app's communication with websites as part of its data organization, Apple went to work to make the fix. Now, a few months after the initial detection, Apple has released a patch with iOS 18.2.
However, Apple can only go so far—the company has delivered the update, but now it's up to you to put it on your phone. To download the latest iOS update on your iPhone or iPad, navigate to Settings > General > Software Update and you should see iOS 18.2 and its description. Tap Update Now.
