If you entered 3 times a wrong code or just forgot it, you can reset your PIN code anytime from your application.
To reset your Mastercard PIN code, select the card from the Cards section.
From the right tab of your screen, click on Reset PIN code and define a new card PIN code. Then, to finalize the activation, you have to complete a first transaction using your PIN, either in-store or at an ATM.
💡If you have set up Strong Customer Authentication on your account, you will receive a confirmation request on your associated phone.
