How to enable biometric login on Kite (Touch ID, Face ID, fingerprint)

Sat, 20 Jun 2026 00:00:00 +0000

Biometric login on Kite uses your phone’s own fingerprint, Touch ID, or Face ID, registered in your operating-system settings, which Kite invokes as device lock at login. It is the second authentication factor for the Kite app, mandatory since 23 September 2022, and the biometric never leaves your phone: Zerodha does not store your fingerprint or face data, it asks the OS to confirm an unlock and receives only a pass or fail. If the scan fails, your phone’s PIN, pattern, or passcode is the fallback.

How to enable device lock on the Kite app

Device lock on the Kite app is your phone’s own screen lock, a PIN, pattern, fingerprint, or Face ID, that Kite uses as the second authentication factor when you log in. It is not a separate code you type into the app and it is not optional: device lock for Kite app login has been mandatory since 23 September 2022, because it satisfies the requirement set by the Securities and Exchange Board of India (SEBI ) for two-factor authentication (2FA) on trading-app login. Your lock data stays on your phone; Zerodha does not store it.

How to fix Kite logging out when switching apps

Sat, 20 Jun 2026 00:00:00 +0000

The Kite app logs you out when you switch to another app, such as an authenticator app to copy a time-based one-time password (TOTP), because your device is in power-saving mode or is preventing Kite from running in the background; the operating system kills the backgrounded app and drops your session. Per Zerodha’s own support article, this is a power-management behaviour, not a deliberate security lock that triggers on app switch. The fix is to stop the OS from suspending Kite: turn off power saving, exempt Kite from battery optimisation, or sidestep the switch entirely by using device-lock biometric login instead of TOTP.
