How to enable 2FA for Arduino

Install Authy

The best way to manage all your 2FA accounts is to use the Authy app. It enables you to have a single mobile app for all your 2FA accounts and you can sync them across multiple devices, even accessing them on the desktop. Install Authy on your device by searching for it in your device’s app store.

Important: If any sites prompt you to use Google Authenticator for two-factor authentication, note that you can always substitute the Authy 2FA app instead. Although they work in similar ways, Authy is more feature-rich and allows for multi-device syncing, cloud-backups, and easier account recovery should you change or lose your phone or device. Read more information on the features of Authy here.

Locate 2FA

When logged into your Arduino account, click on “Profile” under your account name on the upper right..

Then scroll down to the “Security” section and clock on “Activate” under  “Two-Step Authentication.”



Enable 2FA

The next screen prompts you to enable your authenticator app by capturing a QR code. Keep this window open as you reach for your phone.


To capture the QR code, launch Authy on your device. Click ‘Add Account’ at the bottom of the screen.

You’ll be prompted to hold your phone up to your computer to ‘Scan QRCode’ and capture the QR code on the Arduino app.

Once the QR code is captured, Authy will display your Arduino account with the appropriate icon. If you desire you can also change the logo or the nickname you give the account right on the Authy app. When ready, click ‘Save’.


Once you save, the Authy app will generate a numeric ‘token’ associated with your Arduino account.

Return to the Arduino site and click “Next”

Finish Setup

Note the 6 digit code displayed on your Authy 2FA app and enter this code in the entry field as shown. Click “Verify”.

Note your single-use recovery code, which you might need if you ever need to login to Arduino without your device. Once you’ve recorded it, click “Next.”


Now your Arduino account is secured with 2FA.

From now on, you will need to use the Authy app when you log in.
