Denglu1-extension: solve password vulnerabilities and optimize user experience

In this paper, a browser extension called “denglu1-extension” is presented, which helps users generate strong passwords and save them to the trusted user agent. The user agent can send the stored passwords to the browser extension to complete automatic login. Furthermore, in order to enhance the user experience, we also developed a captcha recognition module. According to experimental evaluation, denglu1-extension can efficiently avoid password vulnerabilities.
