A system of credential management and identity verification includes a portable input device and an application that, when executed on the input device, authenticates a user of the input device and provides associated credentials to a computing device. The application detects a request for credentials presented by a proximate computing device. Then, the application alerts a user of the computing device to confirm his identity by submitting one of a biometric or non-biometric authenticating input to the input device. The authenticating input is received by the input device and used to verify the identity of the user. If the identity is verified, the application transmits the associated encrypted credentials and mask data to the computing device. The input device may be a pointing device connected wirelessly or via wired connection to the computer. User authentication data is provided to the input device at an initial or predetermined time.
