๐ Command-Line Authentication Flow Simulator (MFA/2FA Training Tool)
The Command-Line Authentication Flow Simulator is a fully client-side tool for visualizing secure login sequences in a professional animated terminal-style interface. Designed for IT teams, SOC personnel, and security trainers, it breaks down the user authentication journeyโincluding username, password, and multi-factor authentication (MFA)/2FA code entryโwithin a dynamic, responsive CLI simulation.
๐จโ๐ป Why Use This Tool?
This simulator makes it easy to demonstrate or train others on important access control concepts without any server setup or actual accounts. It visually represents a secure authentication process step-by-step, including generating and submitting time-based codes (TOTP), with built-in dark/light mode and memory of previous states.
๐ง How It Works
- Upon loading, the tool steps through a username/password prompt
- Simulates waiting for a 2FA app-generated token
- Displays an animated valid token being entered
- Completes login with a success visual
๐ง Persistent Features
- Session Storage for light/dark mode per session
- LocalStorage logs the time of last flow simulation
