As a result, a significant number of attacks have been observed on these systems. As a result, several password-based authentication mechanisms have been proposed to counteract these attacks. Among them, the graphical password scheme is more consistent with smart devices, which are highly graphic-oriented. However, current graphical password schemes are vulnerable to a variety of assaults, including shoulder surfing, smudging, intersection attacks, and reflection attacks. Thus, the paper aims to review recent published papers on android smart phone graphical password and identify used techniques. Moreover, the paper analyzes results to give better understanding for users of such devices to protect their devices from unauthorized access and attacks. Keywords: Android; smart devices authentication; graphical password; Information security; attacks. 1. INTRODUCTION Password protection analysis is an essential aspect of machine and accessible security. Passwords have shown to be a challenging to be chosen by humans and not much used in password schemes, as the method of utilizing mnemonic or randomly created passwords Review Article
