SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Developers building .NET MAUI apps often need a secure, cross-platform way to store lightweight secrets like tokens or API keys. SecureStorage.Default provides a simple API to store, retrieve, and remove values, but correct platform setup and testability considerations matter for robust apps.

Core Features & Use Cases

SetAsync/GetAsync/Remove/RemoveAll API surface via SecureStorage.Default for simple, cross-platform secret storage.
Platform-aware setup guidance for Android, iOS, and Windows to ensure secure storage works out of the box.
DI wrapper service to improve testability and decouple storage access from UI code.
Best practices: serialize complex data to JSON, handle exceptions gracefully, and understand iOS Keychain behavior and Android backups.

Quick Start

Store a secret securely using SecureStorage.Default and read it back when needed.

FAQPage Schema

How do I store and retrieve secrets securely in a .NET MAUI app?▼

Secure storage in .NET MAUI is achieved through SecureStorage.Default, which provides SetAsync and GetAsync methods to store and retrieve string values like tokens and API keys across platforms.

What platform setup is required for MAUI SecureStorage on Android, iOS, and Windows?▼

MAUI SecureStorage requires platform-aware setup for Android, iOS, and Windows to ensure correct behavior. This includes configuring iOS Keychain access and understanding Android backup rules to prevent data access issues.

How can I make SecureStorage testable in my MAUI application?▼

You can improve SecureStorage testability by using a DI wrapper service that decouples storage access from UI code, allowing you to mock storage operations during unit tests.

Can I store complex objects using SecureStorage.Default in MAUI?▼

SecureStorage.Default uses a string-only API, so you should serialize complex data to JSON strings before calling SetAsync and deserialize the JSON after retrieving values with GetAsync.

Why is my MAUI SecureStorage not working or losing data on iOS?▼

SecureStorage issues on iOS often relate to Keychain behavior, where data can be lost if backup configurations or entitlements are incorrect. Handle exceptions gracefully and verify your platform setup.

How do I remove stored secrets from MAUI SecureStorage?▼

You can remove secrets from MAUI SecureStorage using the Remove method for individual values or the RemoveAll method to clear all stored secrets across your Android, iOS, and Windows apps.
