What it does

Generate secure 2FA (TOTP) codes online with Rapid2FA. Compatible with Google Authenticator, Authy, and Microsoft Authenticator. Private and secure browser-side generation.

A secure, fast, and free tool to generate two-factor authentication codes. Go to the security settings of your account (Facebook, Binance, Google, etc.). Choose "Set up authenticator app" and copy the **Secret Key** provided. Paste the secret key into the **Secret Key** field on Rapid2FA. The system will immediately calculate the 6-digit code based on the current time. Absolutely not. All encryption and calculations are performed via JavaScript directly in your browser. Your data never leaves your device. TOTP is time-dependent. Ensure your computer's date and time are set to "Update Automatically." Even a 1-minute difference can cause the code tofrom rapid2fa.com
