## What it is
UICKeyChainStore is an Objective-C wrapper library for the Apple Keychain on iOS, watchOS, tvOS, and macOS, making Keychain APIs as simple to use as NSUserDefaults. It supports access groups, accessibility options, iCloud sharing, Touch ID integration, and shared web credentials.

## Use cases
- store passwords securely in an iOS app
- save auth tokens to the keychain instead of NSUserDefaults
- use Touch ID to protect keychain items
- share keychain items across apps via access groups
- sync credentials across devices with iCloud keychain
- store internet passwords for a server in a macOS app

## When to choose
- you need simple, NSUserDefaults-like keychain access in Objective-C
- you need Touch ID or shared web credential support on iOS 8+
- you target iOS, macOS, watchOS, or tvOS with a lightweight dependency

## When to avoid
- you are writing Swift and prefer the author's newer KeychainAccess library
- you need cross-platform secure storage outside the Apple ecosystem
- the project needs actively developed features, as this library is in maintenance mode
