Various systems and methods for secure transactions using a personal device are described herein. A system to secure transactions using a personal device, the system comprises a randomization module to randomize an initial keypad representation to produce a randomized keypad representation; a communication module to: receive from the personal device, an indication to begin a secure transaction to access a resource with an access code; and transmit the randomized keypad representation to the personal device for presentation by the personal device to a user of the personal device; a keypad to receive a series of key presses from the user, the key presses corresponding to the access code based on the randomized keypad representation; and a security module to verify that the series of key presses correspond to the access code.
