Stop Using Async Storage to Store Tokens| React Native

In the realm of mobile app development, the quest for secure authentication mechanisms is paramount. As developers, the responsibility of safeguarding user data, especially access tokens, requires a careful consideration of storage options. In this article, we delve into the age-old debate: Should you trust AsyncStorage with your precious tokens, or does react-native-keychain hold the key to ultimate security?

Dont Use Async Storage To store Tokens

Understanding the Contenders:

1. AsyncStorage:

• Simplicity at its Core: AsyncStorage, the go-to storage solution for React Native, is a simple and lightweight key-value store.
• Cross-Platform Compatibility: Its cross-platform compatibility ensures a hassle-free experience across both iOS and Android.

2. React-native-keychain:

• Fortress of Security: Tailored for sensitive data, react-native-keychain employs the secure keychain services of iOS and Android, providing a robust vault for access tokens.
• Platform-Specific Sophistication: With the ability to leverage biometric authentication on iOS and other platform-specific security features, it stands tall as the guardian of sensitive information.

Security Showdown

The battleground for access token security involves two contenders with different approaches. AsyncStorage, the friendly neighborhood store, and react-native-keychain, the armored fortress. Let's explore how each tackles the critical issue of securing access tokens.

AsyncStorage:

• The Simple Solution: AsyncStorage offers simplicity and ease of use, making it the preferred choice for non-sensitive data.
• A Word of Caution: However, its lack of encryption and focus on simplicity might render it less suitable for securing critical information like access tokens.

react-native-keychain:

• Guarding the Gateway: react-native-keychain is built for security, utilizing the device's secure keychain services and offering a layer of protection that surpasses AsyncStorage.
• Biometric Brilliance: The integration of platform-specific security features, such as biometric authentication on iOS, adds an extra layer of defense.

User Experience and Platform Harmony

The battle isn’t just about security; it’s also about delivering a seamless user experience. Let’s explore how both contenders fare in terms of user interaction and platform-specific capabilities.

1. AsyncStorage:

• Ease of Use: AsyncStorage is beginner-friendly, offering a straightforward storage solution.
• The Cross-Platform Advantage: Its cross-platform compatibility ensures uniformity in user experience across different devices.

2. react-native-keychain:

• Sophistication in Interaction: react-native-keychain brings sophistication to user interaction, with the potential for biometric authentication on iOS devices.
• Platform-Specific Enhancements: The library harnesses platform-specific features, contributing to an enriched and platform-tailored user experience.

Conclusion: In the arena of securing access tokens in React Native, the choice between AsyncStorage and react-native-keychain hinges on the nature of the data and the level of security required. While AsyncStorage offers simplicity and cross-platform ease, react-native-keychain stands tall as the fortress of security, providing a robust shield for sensitive information.

As you embark on your journey of securing access tokens, remember that the choice between AsyncStorage and react-native-keychain is not one-size-fits-all. Consider the needs of your application, the nature of the data at hand, and the user experience you wish to deliver. The battle rages on, but armed with this knowledge, you can make an informed decision that aligns with the security standards your app demands.
