Overview
Authentication bypass in mobile applications usually happens when access decisions depend too heavily on client-side logic, local state, or predictable application behavior.
Android apps often contain login screens, session checks, role checks, and feature gates inside code that can be inspected during testing. A secure design should treat the mobile client as an untrusted environment and enforce critical decisions on trusted backend systems.
In this lab, you practice analyzing an Android authentication flow, identifying where trust decisions are made, and understanding why client-side checks alone are not enough to protect restricted functionality.
