OTP or One-Time Password is a security mechanism that helps protect your account.

The default setting of your account is that you will receive an email on a login attempt and you will have to click a link in that email to authenticate the login.

OTP is usually an app you download on your phone such as Google Authenticator or Authy that replaces this process. The app provides a 6 digit code that changes every minute. You will need to enter this code when logging in to your account. Using OTP results in a higher level of security for your account.

To enable your Token/OTP go to profile > settings > security.
