Systems and methods for facilitating a purchase are described. A user logs in to a payment service provider site. The user provides authorization to use a one-page checkout service. The user's information is captured during the session, and a cookie is placed on the user's device. When the user goes on a merchant website and checks out using the payment service provider, the payment service provider detects the cookie on the user device. The payment service provider uses the cookie, and in one embodiment, centrally stored information, to populate the one-page checkout page with the last used payment. In various embodiments, the one-page checkout page also displays a shipping address.

Method, system, and medium for one-page checkout

There is provided systems and methods for passwordless authentication through use of device tokens or web browser cookies. A user may enter into a checkout process with a merchant for a transaction requiring electronic transaction processing with a service provider. The checkout process may be performed prior to or without the user having previously established an account with the service provider for electronic transaction processing. The user may therefore provide user information, such as a name and financial information, and an account for the user may be established. To establish the account, the user is not required to enter a password, and the password is automatically set by the service provider. The service provider may then establish a token on the user's device during transaction processing that later authenticates the device for use of the account during future transaction processing when the token is received.

One-page checkout

Systems and methods for facilitating a purchase are described. When a payment processor declines a transaction, an error code is sent to a merchant. The error code indicates to the merchant that the failed transaction is recoverable if the user chooses a new funding source or payment instrument. The merchant sends the user back to a payment service provider site where the user can either choose a new funding source or enter a new payment method.
