Disclosed herein are system, method, and computer program product embodiments for customizing a user interface on a remote control (or other device, such as a display device or mobile device) based on biometrics of the user. In a non-limiting embodiment, a method operates by receiving an interaction by a user of the remote control, wherein the interaction relates to a biometric of the user. An identity of the user is determined based on the interaction. Information associated with the determined user identity is accessed. Then, the user interface on the remote control is customized based on the accessed information. The biometric may be, for example, associated with a finger size of the user, or associated with motions made by the user with the remote control in forming the interaction. In an embodiment, the user identity is verified by comparing a date/time of the interaction with viewing history of the user, and/or by comparing the date/time of the interaction with a schedule of the user.
