Lock Kuber, private notes and saved cards behind fingerprint or face unlock, secured by your phone.

Biometric Lock screenshot: Privacy and security settings with Biometric Lock switched on

Lock Kuber and sensitive financial sections behind your device hardware authentication:

  • Fingerprint and Face Unlock: Secure your finances with biometric sensors built into your smartphone for rapid, friction-free access.
  • App-Wide or Section Locks: Require authentication when opening the app, or gate specific sensitive tools such as Kuber Notes and Kuber Cards.
  • Hardware-Level Keystore: Powered directly by Android BiometricPrompt APIs and secure hardware enclaves.
  • Zero Exposure: Biometric templates never enter the application. Authentication is handled entirely by your operating system, keeping your identity private.
