As part of the latest beta version of Chrome 95, Google announced the inclusion of a feature for secure payment, basing its operation on connecting to the web authentication API in order to implement an additional web-based layer of security.
The feature adds a new “payment” extension to such an API, allowing institutions such as banks to optionally offer a PublicKeyCredential. A seller or service provider can query this credential during payment transactions through the Payment Request API using the “Secure Payment Confirmation” payment method.
Secure payment confirmation enables FIDO-based authentication. Users enroll a payment instrument using biometric data on the device, in addition to creating a FIDO credential that can be delivered to a payment service provider, such as Stripe; this credential can be used in subsequent transactions for users authentication.
This new feature can also generate a signed challenge that includes the value of the transaction. According to Google, in the testing stage the secure payment confirmation “provided a higher conversion rate and faster authentication time” than the latest version of 3-D Secure authentication flows.
Google also claims that this approach is considered to be a more efficient and secure method than WebAuthn and other alternatives for browser-based authentication. This technology comes at a very opportune time, considering that entities such as the European Union are establishing stricter measures for the support of online payments.
The beta version of Chrome 95 was released a week ago, while the most recent general version of Chrome will arrive to browser users on October 19; this release will remove the U2F API for interaction with security keys.
The beta version has also got rid from support for FTP URLs, a little-used legacy technology that has been replaced by more efficient FTP clients.
