Both your app and the service generate the same code based on time.

4

Frequently Asked Questions

Yes, this Two-Factor Code Generator is completely free to use with no signup required. You can generate as many 2FA codes as you need.
Absolutely! All code generation happens directly in your browser using JavaScript. Your secrets are never sent to any server, ensuring complete privacy and security.
This tool uses the standard TOTP algorithm (RFC 6238), which works with Google Authenticator, Authy, Microsoft Authenticator, LastPass Authenticator, 1Password, and any other authenticator app that supports TOTP.
When you enable 2FA on a service, they usually provide you with a secret key (often shown as a text code or QR code). You can enter that secret here to generate codes. If you're setting up 2FA, use the demo secret to test how it works.
TOTP (Time-based One-Time Password) uses the current time to generate codes. The 30-second window is the industry standard - it provides a good balance between security and usability. Each code is only valid for 30 seconds.
This tool is great for testing and backup purposes, but for daily security, we recommend using a dedicated authenticator app on your phone. However, this tool is perfect for verifying your 2FA is working or as a backup when you don't have your phone.
