Generate Secure 2FA Codes Online
This free tool helps you generate secure authentication codes using the Two Factor Authentication (2FA) standard directly in your browser. No accounts, no tracking, and no stored data.
⚠️ This tool works entirely on your device. Your secret key is never stored or sent anywhere.
What Is Two Factor Authentication?
Two Factor Authentication (2FA) is a security method that adds an extra layer of protection to online accounts. Instead of relying only on a password, users must also enter a temporary verification code that changes every few seconds.
These codes are generated using a secure standard known as Time-based One-Time Passwords (TOTP). Each code is valid for a short time, making it extremely difficult for attackers to reuse or guess.
This website allows you to generate 2FA codes locally in your browser for educational and personal verification purposes. All calculations happen client-side, ensuring maximum privacy and security.
Two Factor Authentication is widely used by email services, cloud platforms, financial applications, and many other online services to prevent unauthorized access.
