Frequently Asked Questions

What is “Citi Mobile® App with enhanced security”?

We have updated the Citi Mobile® App with enhanced security capabilities to provide you with a more convenient and seamless mobile banking experience. This will enable you to proceed with your transactions seamlessly and securely on this device without having to enter the Unlock Code or SMS OTP.

What is the benefit of this enhanced security on my Citi Mobile® App?

When you log in (using biometrics authentication or UserID and Password) to your Citi Mobile® App with the enhanced security capabilities, we will be able to recognize and authenticate you seamlessly.
