Re-enable Touch ID Sensor
Every 90 days, for security purposes, the Touch ID Sensor will be disabled. Therefore customers must re-enable it, using the following required steps, if they have not logged onto the app by using the password for 90 days.
Log on to your Citi Mobile® App and go to "Settings" (located at the top of the navigation menu). Tap on "Manage Touch ID Sensor".
Tick the checkbox after reading the T&C. Tap on "Enable".
You will receive an One-Time Password (OTP)*, which will be sent to you via SMS. Enter the OTP and tap "Continue" to complete the process. When you open the app next time, you can use your fingerprint to log in.
* If you have a security device, please generate a Password using the security device.
