🔐 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 journey—including username, password, and multi-factor authentication (MFA)/2FA code entry—within a dynamic, responsive CLI simulation.
👨💻 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.
🔧 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
🧠 Persistent Features
- Session Storage for light/dark mode per session
- LocalStorage logs the time of last flow simulation
