5 juin 2026 mis à jour

L'authentification à deux facteurs (2FA) protège votre compte Facebook même en cas de fuite de votre mot de passe. Suivez les étapes ci-dessous pour générer des codes de vérification Facebook avec le Authenticator App sur votre iPhone, iPad ou Mac.

Download Authenticator App
Download Authenticator App from the App Store on your iPhone, iPad or Mac. It's free and no sign-up is required.
Open Facebook security settings
Go to “Settings & privacy” → “Settings” → “Accounts Center” → “Password and security”.
Choose two-factor authentication
Select “Two-factor authentication”, pick your account, then choose “Authentication app”. Facebook will display a QR code.
Scan the QR code with Authenticator App
Open Authenticator App, tap the + button and scan the QR code shown by Facebook. If you can't scan it, choose the manual option on Facebook and type the setup key into the app instead.
Enter the 6-digit verification code
Type the 6-digit code from Authenticator App back into Facebook to confirm the setup. The code refreshes every 30 seconds.
Save your backup codes
If Facebook offers backup or recovery codes, download or write them down and store them somewhere safe. They let you regain access if you ever lose your device.
