How to enable two-factor authentication and two-password mode

With ProtonMail, users have the advantage of counting on with a secure, encrypted and powerful email solution that guarantees confidentiality and privacy online. This is the main focus of this platform, by protecting users through encryption technologies at a hardware and software level, with secured servers in Switzerland and protocols that keep personal information unreachable.

In the same way, ProtonMail allows you to enable different features that add extra security layers of protection and avoid unauthorized access. Two of these functions are the two-password mode and the two-factor authentication. This is how you can configure these options and put them to good use.

Two-factor authentication in ProtonMail: How to set it up

To begin with, the two-factor authentication is an extra layer of security, and when enabled users will be prompted by the platform to enter a 6-digit code every time they log in. Therefore, even if the password is compromised, intruders will be requested with a code they do not have and the account remains safe.

Follow these steps to enable two-factor authentication in ProtonMail:

  • Open session in ProtonMail. Click here and then click on “Log in” and sign in using your username and password.
  • In your inbox, click on the “Settings menu” button and then on “Go to settings”, at the top right corner.
  • In the Settings, click on the “Password and recovery” category on the left.
  • In the Passwords subcategory to the right you will be able to see the Two-factor authentication option. Click on the switch icon to start the configuration process.
  • A prompt window will appear telling what a two-factor authentication is. Click on “Next”.
  • On the next screen, ProtonMail will ask you to scan the QR code with your mobile device using a compatible two-factor authentication app. Google Authenticator is recommended.
  • If the scan is correct, ProtonMail will ask you to enter your password and the two-factor authentication code shown by the app. Click on “Submit” after all fields are entered.
  • Since all information is valid, the two-factor authentication option is now enabled. This means, every time you open session in ProtonMail, you need you password and also a 6-digit code generated by the two-factor authentication app, such as Google Authenticator.

Enabling the two-password mode in ProtonMail

The two-password mode in ProtonMail, as the name says allows to open session using two passphrases, adding an extra layer of protection. Follow these steps to do it:

  • Repeat the first three steps of the previous configuration process.
  • In the Password subcategory, click on the switch icon respecting the Two-password mode field and the configuration process should start.
  • The platform will ask you to enter your old password and set a new one, which is the login password. Click on “Save” after completing each field.
  • Now, establish your mailbox password so your messages can be decrypted when sign in.

Enter your mailbox password, confirm it and then click on “Save”.

  • The two-password mode is now enabled and two passphrases are required to sign in.
