      abstract = {Review on the use of emojis as an alternative to PIN entry and text passwords was conducted by analyzing the current state of emoji-based authentication. Mobile devices store a lot of personal data and despite all the technological progress, the usability and security of mobile authentication mechanisms did not significantly evolve, as a consequence, data protection is still an annoying and sometimes difficult task which requires an active contribution of the user.  This Work explores emojis as graphical password alternative for user authentication. Most of the graphical authentication schemes provide longer authentication times and therefore emojis were chosen to be the alternative to reduce the lengthy authentication time and improve the memorability of the password. The usability and security evaluation have been conducted from a designed prototype system of emoji face (EF), passface (PF), animal emoji (AE), real animal (RA), food emoJI (FE), real food (RF), Object emoji (OE) and real object (RO) using java programming language. This is done to explore the differences among efficiency, effectiveness, and user preference. The findings showed an acceptable level of efficiency, effectiveness and user satisfaction of the proposed system. The emoji passwords Ware easy to remember, password creation and login are fast, and a positive user experience is also recorded. However, certain emojis were preferred by the participants.},
