Methods, systems, and computer program products for secure cardless cash withdrawal are provided. A computer-implemented method may include identifying one or more cash machines near a computing device of a user, receiving a cash request from the computing device, generating a one-time authorization code on a secure server for the cash request when the computing device is detected by a sensor of a selected cash machine, providing the one-time authorization code to the computing device for display to the user when the computing device is detected within a distance allowing the user to operate the cash machine, validating a user-provided code received from the selected cash machine in view of the one-time authorization code, instructing the selected cash machine to distribute the requested cash when the user-provided code is validated, and invalidating the one-time authorization code when the cash request is completed.
