Various embodiments are directed to systems and methods enabling cardless cash withdrawals from ATMs and/or other funds dispensing system. In various embodiments, a finite-duration access code is generated and associated with an account from which funds are to be withdrawn in response to a validated request generated at a mobile app operating on a user's mobile computing device. The access code is provided to the user (e.g., via the mobile app), who can then provide the finite-duration access code and an associated PIN to the funds dispensing system. The funds dispensing system transmits the received access code and/or PIN to servers to validate the request. The servers compare the transmitted data against stored data associated with the user's account, and generates a verification response to be transmitted to the funds dispensing system upon verification. The funds dispensing system then provides the requested cash to the user.
