4 Reasons Not to Install iOS 15.8.2 & 10 Reasons You Should

Install iOS 15.8.2 for iCloud Keychain Improvements

iOS 15.4 brought several improvements to Apple's iCloud Keychain feature. If you use iCloud Keychain, and you missed iOS 15.4 and newer, you should probably download iOS 15.8.2.

The first change is the ability to add notes to password entries. This brings it level with popular alternatives like LastPass and 1Password.

The other addition is a way to hide password alerts. This is useful if you keep getting recommendations from Apple about a weak or compromised password that you can't change. 

You can simply tap the x to dismiss/hide the notification. And if you want to bring the notification back, you'll find it in the Hidden Security Recommendations in the Password settings.
