People today frequently find themselves maintaining many accounts across various social platforms, e-learning websites, and logins for their place of employment. It might be time-consuming and difficult to manually log into each account, which requires entering the necessary credentials manually. Another difficult issue is having to remember a variety of user IDs and passwords for each platform. The proposed system is an Attiny85-based USB device. Using encryption, the user’s information including the login credentials is secured. Comprehensive testing is done to assess the efficiency and usability of the proposed automated login system, taking into account elements like login speed, accuracy, security, and better user experience. The credentials are stored on the IC which makes it impossible for any other person to access or hack the data.
