Android Keystore vs Shared Preferences

Developers should use Android Keystore when building apps that require secure handling of cryptographic keys, such as for encrypting user data, implementing biometric authentication, or signing API requests meets developers should use shared preferences when they need to persist small, simple data like user settings, login tokens, or app configuration without the overhead of a database. Here's our take.
