How FastAuth works

Complete checkout in three simpler stages.

Saved details are reused

FastAuth can securely autofill previously saved customer information so the shopper does not need to re-enter the same details each time.

Payment is completed

The shopper confirms the purchase using a supported payment method while the merchant keeps transaction activity visible through the connected checkout workflow.

Connected checkout

FastAuth connects shopper context, saved information, payment choice, gateway processing, security, and reporting into one streamlined checkout experience.
