The increase in Android devices has made mobile authentication an important security issue. Traditional password systems are falling short against more complex attacks. This review looks at the development of authentication systems for Android mobile devices, focusing on improved methods that go beyond typical password approaches. We examine eight key research contributions from 2010 to 2024. These cover topics like behavioral biometrics, graphical password systems, touch- based authentication, gait recognition, vulnerability detection, and security protection methods. Our findings show a clear shift from static authentication methods to dynamic, multi-modal approaches that use smart- phone sensors and user behavior. We highlight key challenges, such as the trade-off between accuracy and usability, vulnerability to shoulder surfing, and the need for ongoing authentication. We suggest a unified framework to categorize these systems based on their mechanisms while evaluating their strengths and weaknesses. This work offers insights for future research in mobile authentication, stressing the importance of combining different biometric methods with traditional security measures.
