What is two-factor authentication?
Two-factor authentication (2FA), also known as 2-step verification, is a security layer in addition to your email and password. You will need to provide your 2FA code when signing in to your account, withdrawing from OpenNode or enabling instant exchange functionality.
How can I use two-factor authentication?
We recommend using Google Authenticator or Authy.
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.
What if I don’t have a smartphone?
If you do not have a mobile device that supports Google Authenticator or similar apps, you can install a TOTP app on your computer and configure it with the secret seed provided during 2FA setup.
What is a secret key?
When you setup two-factor authentication, you'll 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.
