Ionic Identity Vault: Secure Mobile Biometric Authentication

1. Firebase Auth for Capacitor

Firebase Authentication offers a powerful way to manage secure sessions for Capacitor apps. By integrating Firebase’s native SDKs (Swift for iOS, Java for Android) alongside the Firebase JavaScript SDK for web, it ensures a smooth and consistent authentication experience across platforms [4].

Here are some of the standout security features:

These features establish a solid security framework, enabling developers to enhance it further with measures like token revocation and multi-factor authentication.

Firebase projects are identified by API keys, but securing access depends heavily on properly configured Firebase Security Rules [5]. To strengthen security, developers should follow these practices:

• Revoke tokens during logout to prevent unauthorized access.
• Enable Multi-Factor Authentication (MFA) for sensitive accounts.
• Configure protection against email enumeration attacks.

Sharathdev’s December 2023 analysis highlighted that implementing token revocation during logout can significantly reduce the risk of account takeovers [6].

The plugin supports both native and web authentication flows. However, for mobile apps, native authentication is the preferred option due to WebView’s inherent limitations [4].

When compared to other session management tools, Firebase Auth stands out with its easy integration and extensive security features, making it an excellent choice for Capacitor apps that demand strong authentication capabilities.

2. Biometric Security Plugin

The Capacitor Biometric Security Plugin allows developers to integrate biometric and device credential authentication into their apps, ensuring secure user sessions. It supports various authentication methods, including biometric options like fingerprint, face recognition, and iris scanning, as well as device credentials such as PINs, patterns, and passwords. This functionality is available for both Android and iOS platforms [7].

Configuration Example

Here’s an example of how you can define the plugin settings:

const options = {
  allowDeviceCredential: true,
  androidBiometricStrength: 'WEAK',
  title: 'Verify Identity',
  subtitle: 'Use biometrics to access your account',
  cancelButtonText: 'Cancel Authentication'
};

Platform-Specific Setup

To implement the plugin, you’ll need to make some platform-specific adjustments:

• iOS: Add NSFaceIDUsageDescription to the Info.plist file to explain why Face ID is being used.
• Android: Include the android.permission.USE_BIOMETRIC permission in the AndroidManifest.xml file.

These steps are essential for ensuring the plugin works seamlessly and aligns with secure session management strategies [8][10].

“Every Capacitor developer is responsible for making sure their app is following security best practices. Without proper care, major security issues can crop up which can prove extremely damaging and expensive.” – Capacitor Documentation [1]

Key Features and Updates

The plugin includes functionality to check for biometric availability, enrollment, and device credentials using methods like isAvailable(), isEnrolled(), and hasDeviceCredential(). Additionally, developers can encrypt tokens using platform-specific secure storage solutions, such as iOS Keychain and Android KeyStore, to enhance security [11].

Version 9.0.0, released in April 2025, introduced compatibility with Capacitor 7 and included improvements for iOS [9].

Advanced Security Measures

To further secure sessions, developers should implement automatic session timeouts and monitor for biometric changes. If changes are detected, authentication tokens should be invalidated to prevent unauthorized access [11]. The plugin also features a detailed error-handling system, providing feedback codes that help developers create fallback mechanisms and inform users when authentication fails [8].

This plugin offers a robust solution for integrating biometric security into modern apps, ensuring both convenience and protection for users.
