If you use only Citi Mobile to access your accounts, please ensure you select your User ID here with your active Internet Password (IPIN). After this one time process, you will be able to continue accessing Citi Mobile with ease.
For Citibank payment gateway users, you will be able to authenticate your Online purchase transactions without choosing a User ID until an interim transition period. Post this period, you will mandatorily be required to select your User ID, for using the IPIN for authenticating your purchase transactions. After you select your User ID, you will just be required to enter your IPIN to authenticate your transaction. However even if you have not chosen your User ID, the option to request for an OTP and use the OTP to authenticate your transaction will continue to be available.
This transition date will be communicated separately.
