KAIST One Click Service is a Chrome extension designed to streamline the two-factor authentication process for university site logins. This free tool automatically retrieves the authentication code from designated email services, such as Naver and Gmail, allowing users to bypass the manual steps of opening their email and copying the code.

The extension operates by logging into the specified email service and automatically entering the authentication code sent to the user's inbox into the university's login page. Users should note that this program is intended exclusively for personal computers, as using it on shared devices may risk exposing sensitive information like usernames and passwords. This feature enhances convenience while maintaining a focus on user security.
