Smartphone is the most widespread devices due to their various built-in features, portability and real-time message sharing among the gadgets used by human. Smartphone authentication is needed in order to protect users private information and also to prevent any non-restricted access. This paper introduces a novel and user-friendly smartphone locking system called the Analog clock-based locking system. The Analog Clock-Based Locking System (ACBLS) aims to provide a convenient and secure user experience, combining simplicity and enhanced security in a single solution. This technique unlocks the device using time-based codes established on an analog clock rather than regular PIN numbers or passwords. By aligning the exact time on the analog clock, users can securely access their smartphones. This study explores the principles, design factors, and potential benefits of this new clock-locking system. It also examines the technical feasibility and potential challenges of applying it to smartphones. This research contributes to smartphone security and user interface design by offering a novel method for locking mechanisms.
