What is the 3D Secure service?

  • The VISA Secure & Mastercard Identity Check services are available to VISA & Mastercard cardholders and are a necessary step during the use of the Card for online purchases within the European Economic Area. This is in line with the Banks’ obligation to implement Strong Customer Authentication (SCA) in electronic transactions (EU Directive 2015/2366 on payment services, which has been incorporated into Greek legislation with Law No. 4537/2018 [Government Gazette A 84/15.5.2018] and under the authorization of Regulation 2018/389 of the European Commission). The service can only be used for online purchases from businesses that are certified in the VISA® SECURE™ & Mastercard® Identity Check™ Service.

How the service works:

From now on, before completing your online transaction with your credit or debit card, a notification will appear on your screen with the details of the transaction:

  • The name of the merchant

  • The amount

  • The date and time of the transaction

  • The last 4 digits of your card number

  • Your mobile phone number

Verification of your details with strong authentication

To complete your transaction, your identity will be verified through strong authentication by entering two codes, as shown in the image below:

  • a. A One-Time Password (OTP) code, which you will receive via SMS on the mobile number you have registered with the Chania Cooperative Bank. Enter this code in the corresponding field of the notification within a time limit of three (3) minutes. After three minutes, the code will expire. You have the option to select “Resend SMS” if needed.

  • b. Your personal code. On your first transaction, you will enter your Tax Identification Number (TIN – ΑΦΜ).

Next, after entering the SMS OTP and your TIN (ΑΦΜ), you will be prompted to change your personal (static) password to one of your choice, on the page that will automatically appear. The personal code you create will be used for your future online transactions.

After your identity has been verified with strong authentication, your payment will be forwarded for approval.
Please note that without your mobile phone, completing your transaction will not be possible.

If, for technical reasons, you are unable to receive the SMS—either because your mobile phone number is incorrect or because you have not provided it to the Bank—you must visit one of our Bank’s branches to update your personal information.

  • With the VISA Secure & Mastercard Identity Check service, your online transactions with your card are now verified through identity authentication, applying the upgraded EMV 3DS security protocol.

    This way, your transactions are secured, and the risk of fraud in online transactions made with your card is reduced.

Frequently Asked Questions and Answers about the 3D Secure Service

The One-Time Password is sent to the mobile phone number you have registered with the Bank, providing you with additional and enhanced security for online transactions.

The personal password adds an extra layer of security to your online transactions. This password is initially your Tax Identification Number (TIN) as registered with the Bank. During your first transaction attempt, you will be prompted to change it and use the new personal password for future transactions. If you wish to keep the same personal password, you must enter your TIN twice, and it will then be saved as your personal password.

To complete an online transaction at a certified online store, your identity must be verified using a One-Time Password (OTP). The OTP is sent to the mobile phone number you have registered with the Bank, and you will need to enter it on the screen that appears—after first confirming the transaction details are correct. If no mobile phone number is registered, you will need to visit a Bank Branch.
