Security

Jailbroken/Rooted devices can access your iOS' Keychain and Android's shared preferences in plain text, so it is necessary to add another layer of protection.

• iOS: it is implemented through Access Control. Everytime the app wants to access the protected keychain item, a prompt by iOS will show up. Only after authentication success will return the requested item.

• Android it is implemented through FingerprintManager + Keystore . Keystore has a function called setUserAuthenticationRequired which makes Keystore requires user authentication before getting value.

• Windows: it is implemented using PasswordVault. Only the App itself can access the data stored in its Password Vault.
