Passgorithm is a Flutter mobile application that solves the security problem of password reuse across platforms by helping users create different, complex passwords through a single, customizable algorithm. Users can craft personalized password algorithms by combining dynamic inputs (app name, category, email), static personal inputs (username, job title, nationality, etc.), and operations (insert, rotate) to generate unique passwords on demand. The app integrates with Firebase for authentication and cloud-based algorithm storage.
