MS Authenticator App

How to enable 2FA on Dynu

Dynu overview Supported

Enable two-factor authentication on Dynu to stop unauthorized logins. After setup, Dynu asks for a rotating code from MS Authenticator App in addition to your password.

Step-by-step setup

  1. 1

    Sign in to Dynu and open your Dynu 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 Dynu 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 Dynu account.

  5. 5

    Save your backup codes.

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

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