Registered customer on an unrecognized device

Learn more about the Click to Pay checkout flow for a registered customer on an unrecognized device.

Overview

For customers with a Click to Pay profile using an unrecognized device during checkout, they must enter the email address associated with their Click to Pay account. To complete the verification process, they will receive an OTP on the email or mobile number that they have previously registered for Click to Pay. The OTP is requested for the first time, and there is an option to remember the device in the browser, eliminating the need for email or OTP for future transactions.
