Two-factor authentication (2FA), also known as 2-step verification, is a security layer in addition to your email and password. Once set up, 2FA is required when signing in to your account, withdrawing funds from OpenNode, or changing advanced payments settings.

We recommend downloading and using Google Authenticator (App Store / Google Play).

By using Google Authenticator or another authenticator app, the only way to access the codes is via physical access to the device running the app.

If you do not have a mobile device that supports Google Authenticator or similar apps, you can use a TOTP app on your computer and configure it with the secret seed provided during the 2FA setup. 

When you set up 2FA, you will be prompted to write down and save your secret key. If you lose access to your phone, you can authenticate using this secret key. We recommend that you store your key in a very safe place. Generally, your secret key will help you get back into your account if you ever lose access.

Your secret key will look like this:

If you lose your secret key but still have access to your authentication device, you are able to reset your secret key. This requires you to have access to your current authentication device.

If you have lost your secret key and don't have access to your authentication device, please email support@opennode.com or use the chatbox to get help.
