5 juin 2026 mis à jour

L'authentification à deux facteurs (2FA) protège votre compte Google même en cas de fuite de votre mot de passe. Suivez les étapes ci-dessous pour générer des codes de vérification Google 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 your Google Account settings
On a computer, go to myaccount.google.com, or click your profile picture and choose “Manage your Google Account”.
Go to Security and open 2-Step Verification
Select “Security” in the left menu, then under “How you sign in to Google” click “2-Step Verification” and follow the prompts to turn it on.
Choose the Authenticator app option
From the list of second steps, find “Authenticator app” and click “Set up”. Google 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 Google. If you can't scan it, choose the manual option on Google 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 Google to confirm the setup. The code refreshes every 30 seconds.
Save your backup codes
If Google 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.
