Masterkey allows using Passkeys for other actions other than signing

      Using your Mastercard payment passkey is easy:

        STEP 1: Select your Mastercard

          Choose your Mastercard when checking out as a guest or using your card stored at participating merchants.

        STEP 2: Confirm your payment

          You will be prompted to use the authentication mechanism available on your device (e.g., fingerprint).

        STEP 3: Complete checkout

          Upon successful authentication, your payment is completed.

    Authentication can be the PIN

      Payment passkeys allow you to authenticate your online purchases using your fingerprint, face scan or PIN on your personal device.
