When you first set up 2FA for your Proton Account, we provide several one-time use recovery codes. Please save these codes in a secure place and do not lose them. If you lose your device, you can enter these codes instead of the 6-digit code usually provided by an authenticator code app. You can only use each code once. Using a 2FA code doesn’t disable 2FA for your Proton Account, so once you’ve signed in, be sure to turn it off. You can then set up 2FA with your replacement smartphone or another device.
