Many mobile apps face challenges in implementing secure biometric authentication and storing sensitive data, often resorting to inadequate methods such as simply displaying biometric prompts or storing data unencrypted. These common mistakes, such as not using biometric APIs properly or failing to encrypt sensitive information at rest, can expose apps to security risks, especially on jailbroken devices. The gold standard for mobile security involves using comprehensive security APIs on iOS and Android to tie biometric data with encrypted values, ensuring sensitive information is accessible only through genuine biometric authentication. Ionic Identity Vault offers a solution by providing advanced biometric APIs and managing complexities such as user enrollment and device-level encryption, integrating seamlessly with other Ionic enterprise solutions to securely handle authentication tokens and encryption keys.
