Passwords can be lost or stolen. Mastercard Click to Pay uses advanced payment technology built on industry standards and intelligent security to ensure that you, and only you, are accessing your profile. If you're a remembered user, you'll be recognized at checkout – no verification code required. If you’re not a remembered user, enter your user ID – the email address associated with your payment profile – to receive a verification code. This will allow you to access your payment profile and check out securely in just a few clicks. For additional security, verification is always required to update personal information. You may also need to provide verification if there is unusual activity with your payment profile.
