ios - 每个 iOS 应用程序在设备上都有自己的单个钥匙串(keychain)吗？

Question

我真的很困惑，因此问这个问题 - 每个 iOS 应用程序在设备 (iPhone) 上都有自己的钥匙串(keychain)，还是设备 (iPhone) 上只有一个钥匙串(keychain)供不同的应用程序使用？

谢谢

Answer 1

如 Apple 文档中所述。对于 iPhone，只有一个钥匙串(keychain)，应用程序可以在其中存储它们的钥匙串(keychain)项目。

In iOS, apps have access to a single keychain (which logically encompasses the iCloud keychain). This keychain is automatically unlocked when the user unlocks the device and then locked when the device is locked. An app can access only its own keychain items, or those shared with a group to which the app belongs. It can't manage the keychain container itself.
