Embodiments of the present invention may enable a user of an electronic device to setup a game-based environment within the electronic device that can be used as an authentication platform to prevent access by illegitimate or unauthorized users. The communication device may include a display screen, a processor, and a memory coupled to the processor. The memory may include a database and an instruction set. The database may store pre-defined access patterns that can be used in the authentication process. Further, the instruction set may include instructions executable by the processor to monitor inputs made by a new user in the game based environment. Furthermore, the instructions executable by the processor may match the inputs of the new user with the pre-defined access patterns to check the authentication of a new user.
