How to enable 2FA on Tello

← Tello overview Supported

Tello 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 Tello account.

Step-by-step setup

1
Sign in to Tello and open your Tello 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 Tello 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 Tello account.
5
Save your backup codes.
Store the recovery codes Tello gives you somewhere safe — you'll need them if you lose your phone.

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