Mastercard SecureCode is a service that enhances online payment security. When you use your credit, the card company's rules also protect your purchases.
It is based on single-sign-on (SSO) with an SMS without having to log in separately.
If you make a purchase with your Mastercard, a One Time Password (OTP) will be sent to you mobile phone via SMS. Receiving the SMS may take a moment. Enter the OTP in the text message into the network view to confirm the payment. If you enter an incorrect OTP four times in a row, the service will be blocked. In such a case, please contact Mastercard customer service.
If you have not informed your phone number to OP, sign-on will fail. You can check the phone number within the service from the Mastercard SecureCode screen when you make an online purchase.
When you pay for your purchases on the web through the Mastercard SecureCode service, you will go to service window where you accept your purchase in encrypted internet connection using your personal online service user identifiers. This way both the merchant and buyer have been reliably authenticated. You can identify the web shops that use the services with the Mastercard SecureCode logo. The service will cause no extra charges to you.
If you have separately enabled the Mastercard SecureCode at op.fi, signing on will work through the TUPAS authentication service when making web purchases with Mastercard.
