How to enable 2FA on Sync

← Sync overview Supported

Protect your Sync account with two-factor authentication (2FA). Once enabled, signing in also requires a one-time code from your authenticator app — not just your password.

Step-by-step setup

1
Sign in to Sync and open your Sync account security settings.
2
Turn on two-factor authentication and choose the authenticator-app option.
Look for "Authenticator app", "Authentication app", or "TOTP" rather than SMS.
3
Scan the QR code with MS Authenticator App.
Open MS Authenticator App, tap add, and point your camera at the QR code Sync displays. Can't scan? Enter the setup key manually instead.
4
Enter the 6-digit code to confirm.
Type the code MS Authenticator App generates to verify and link your Sync account.
5
Save your backup codes.
Store the recovery codes Sync gives you somewhere safe — you'll need them if you lose your phone.

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