How to enable 2FA on Arduino
Arduino lets you secure your account with an authenticator app. With 2FA on, each login needs a fresh 6-digit code, keeping your Arduino account safe even if your password leaks.
Step-by-step setup
- 1
Sign in to Arduino and open your Arduino 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 Arduino 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 Arduino account.
- 5
Save your backup codes.
Store the recovery codes Arduino gives you somewhere safe — you'll need them if you lose your phone.
Menu names on Arduino can change — the official Arduino 2FA documentation ↗ always has the exact, current path.
Frequently asked questions
- Does Arduino work with authenticator apps like MS Authenticator App?
- Yes. Arduino supports TOTP authenticator apps, so you can generate its two-factor codes in MS Authenticator App.
- Is Arduino two-factor authentication free?
- Yes. Enabling authenticator-app 2FA on Arduino is free — you only need the free MS Authenticator App.
- What if I lose access to my Arduino 2FA codes?
- Use the backup or recovery codes you saved during setup. If you didn't save them, contact Arduino support to regain access, then re-add the account to MS Authenticator App.
