About this tool
Step-by-step Facebook two-factor setup with an authenticator app or security key, recovery codes and a readiness score.
This guide walks through enabling two-factor authentication on a Facebook profile in Meta's Accounts Center, then scores how much lockout and takeover risk is left. Facebook offers three second factors — security key, authentication app and text message — and the checklist adapts to whichever you pick, including saving recovery codes and switching SMS off once a stronger factor works. It is aimed at anyone protecting a personal profile, a Page they admin, or a business account tied to ad spend.

Steps change depending on whether you chose a security key, an authenticator app or SMS.
Unsaved recovery codes and a live SMS fallback drag the score down even when 2FA is technically on.
The checklist runs entirely in your browser — no account details, codes or logins are ever requested.
Go to Settings & privacy, then Settings, then Accounts Center, then Password and security, then Two-factor authentication, and pick the profile you want to protect. Accounts Center handles each linked Facebook and Instagram profile separately, so switching it on for one does not switch it on for the others.
Yes. SMS codes can be stolen by SIM-swap fraud, where an attacker moves your number to their own SIM and receives the codes without touching your phone. A TOTP app generates the 6-digit code on your device from a shared secret every 30 seconds, so there is nothing on the phone network to intercept.
You sign in with one of the one-time recovery codes Meta issued during setup, which is why saving them offline is a required step. Without codes or a second registered factor you have to go through Meta's identity-verification appeal, which can take several days and sometimes needs a photo ID.
Yes, once you have confirmed the stronger factor works and you have recovery codes saved. Any second factor left enabled is a way in, so leaving SMS active means your account is only as strong as your phone number. This is general security guidance, not advice about your specific account.
