Thank you for making Citi Credit Card your preferred credit card. Citibank is committed to providing the best security measures to serve you better. We are currently implementing new measures to enhance the security of online transactions made on your Citi Credit Card with 3D Secure by adding additional layer of authentication in forms of One-Time Password (OTP) which will be sent to your mobile phone every time you want to do online transaction.
Introducing the One-Time Password (OTP) for your online purchases.
Starting 16 Feb 2015, you will be required to key in an One-Time Password (OTP) when you make an online purchase at participating 3 Domain Secure (3D Secure) merchants using your Citi Credit Card. A pop-up screen will appear, prompting you to key in the One-Time Password (OTP) which will be sent to your mobile phone number registered in our system.
What is 3D Secure?
3D Secure is a security protocol used by banks worldwide to authenticate online card transactions. You can recognize 3D Secure merchants by the "Mastercard® Secure Code" or "Verified by Visa" logos on the online merchant’s website.
In order to continue enjoying online purchases at 3D Secure online merchants with your Citi Credit Card , kindly provide us with your latest mobile phone number via Citibank Online or contact our CitiPhone Banking (021) 252-9999, or 62 21 2529999.
