What data should I store in MAUI Secure Storage?

Secure Storage is intended for small strings like auth tokens, passwords, or API keys. You should avoid storing large blobs or general application files; use SQLite or file handling skills for larger datasets.

Does this skill handle Android Auto Backup issues?

Yes, the skill provides specific configuration patterns to either disable backup or exclude the secure preferences file, which prevents decryption errors when users restore their data on new devices.

Why should I use a DI wrapper for SecureStorage?

Wrapping SecureStorage in an interface allows you to mock the storage service during unit testing. This is essential for testing ViewModels and Services without needing a physical device or emulator.

Is data automatically cleared when an app is uninstalled?

Behavior varies by platform: on Android, data is typically removed on uninstall; however, on iOS, Keychain values persist and will be available if the app is reinstalled.

Implements secure credential and sensitive data storage for .NET MAUI applications using platform-native encryption.

This skill provides comprehensive guidance for managing sensitive data in .NET MAUI applications via the SecureStorage API. It facilitates the implementation of secure key-value storage, handles complex platform-specific configurations like Android Auto Backup rules and iOS Keychain entitlements, and provides a production-ready Dependency Injection (DI) wrapper for enhanced testability. It is ideal for developers needing to store auth tokens, passwords, or small secrets while avoiding common pitfalls like data corruption during backup restores or platform-specific storage limits.
