If you're using the Dashlane web app to turn on 2-factor authentication (2FA), you'll find the QR code you need during the set-up process.
Important: If you're using the Dashlane Android or iOS (Apple) mobile app to turn on 2FA, you won't have a QR code. You can use these apps to set up 2FA with the Dashlane Authenticator, but not other authenticator apps.
Start the 2FA set-up process
In the web app, select the My account menu, Settings, and Security settings, and then turn on 2-factor authentication to begin the set-up process.
Find the QR code
The QR code will appear in the third step of the setup process after you've selected your 2FA settings and entered your phone number.
