🛡 3. Facebook How to Enable Two-Factor Authentication (2FA)

5. Extract and generate the verification code:
After the system generates the 2FA secret key (key string), copy it down; you can paste it into the Google Authenticator browser extension on your computer, or directly open a static decoding website in your browser 2fa.live and paste it to extract the 6-digit real-time dynamic login verification code.
⚠️ Note: 2FA dynamic verification codes are time-synchronized, so they are only valid for 30 seconds. If the countdown expires, please click to regenerate on the webpage.
