KeyChain stores data after deletion and reinstallation of the app, while UserDefaults does not.
- UserDefaults stores settings and data in the app container. When the app is deleted, all UserDefaults data are removed.
- KeyChain is a secure storage designed for storing confidential information (passwords, tokens). Data in the KeyChain remains even after the app is deleted, unless the device is changed or the KeyChain is manually cleared.
Therefore, to preserve data between app reinstallations, you should use the KeyChain.
