## Description

This project is a two-factor authentication manager that generates time-based and counter-based one-time passwords to secure online accounts. It functions as an encrypted credential manager for storing authentication seeds and producing security codes on mobile and wearable devices.

The application includes a dedicated Android Wear OS client that synchronizes authentication data and UI states to allow security codes to be viewed directly from a smartwatch.

The system supports the import and migration of authentication seeds from other applications and provides encrypted backup capabilities to local or cloud storage for account recovery. It also includes organizational tools to group authentication entries into custom categories with associated brand iconography.
