MS Authenticator App

How to enable 2FA on Earth Class Mail

← Earth Class Mail overview Supported

Earth Class Mail supports app-based two-factor authentication (2FA). Turning it on adds a second layer of protection, so a stolen password alone can't unlock your Earth Class Mail account.

Step-by-step setup

  1. 1

    Sign in to Earth Class Mail and open your Earth Class Mail account security settings.

  2. 2

    Turn on two-factor authentication and choose the authenticator-app option.

    Look for "Authenticator app", "Authentication app", or "TOTP" rather than SMS.

  3. 3

    Scan the QR code with MS Authenticator App.

    Open MS Authenticator App, tap add, and point your camera at the QR code Earth Class Mail displays. Can't scan? Enter the setup key manually instead.

  4. 4

    Enter the 6-digit code to confirm.

    Type the code MS Authenticator App generates to verify and link your Earth Class Mail account.

  5. 5

    Save your backup codes.

    Store the recovery codes Earth Class Mail gives you somewhere safe — you'll need them if you lose your phone.

Menu names on Earth Class Mail can change — the official Earth Class Mail 2FA documentation ↗ always has the exact, current path.
