Systems and methods for authorizing data transfers are disclosed. Exemplary implementations may: receive a data transfer authorization request based on a data transfer initiated by a customer computing device; when the customer computing device is associated with a system of trust: send a third-party second-factor authentication message to trustee computing device(s) without sending any message to the customer computing device, and authorize the data transfer system to complete the data transfer request in response to receipt of a third-party authentication confirmation from the trustee computing device(s) and in the absence of any authentication confirmation from the customer computing device.
