What to do if you’ve lost your 2FA device

Two-factor authentication (2FA)(new window) greatly improves the security of your account by requiring you to confirm your identity with something you have (such as your smartphone or security key(new window)). Unless an adversary knows your login details and also has physical access to your 2FA device, they can’t access your account.

But what happens if you lose your 2FA device? In this article, we’ll explore ways to recover access to your account if you’ve lost or no longer have access to your 2FA device. 

1. Use 2FA codes

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.

2. Use a recovery method

If you’ve set up a recovery phrase, you can reset your password and then recover your data using your recovery method.

Resetting your password will turn off 2FA for your Proton Account, so we recommend setting up another 2FA device to keep your account secure.
