Step-by-step setup

1
Sign in to Cloud 66 and open your Cloud 66 account security settings.

Turn on two-factor authentication and choose the authenticator-app option.
Look for "Authenticator app", "Authentication app", or "TOTP" rather than SMS.

Open MS Authenticator App, tap add, and point your camera at the QR code Cloud 66 displays. Can't scan? Enter the setup key manually instead.

Enter the 6-digit code to confirm.
