A payment authorization system includes an account database associating a first user device and a payment account. A system provider device in the payment authorization system is coupled to a network and the account database. The system provider device is operable to receive a payment request from a second user device over the network to make a payment using the payment account. In response to receiving the payment request, the system provider device sends an authorization request to the first user device over the network. In response to receiving an authorization from the first user device over the network, the system provider device sends an instruction over the network to make a payment according to the payment request. The first user device may designate the second user device for using the payment account such that a temporary security code is sent to the second user device over the network. |
