Two-factor authentication is now available for all OpenDNS customers in the Umbrella Dashboard at OpenDNS.
Three main methods:
1. Hardware Tokens have a secret key, then calculate security tokens that they normally display on a screen. These types of devices have been a common sight on the keychains of banking employees for decades.
2.In an SMS-based system, the server generates the token, sends it to the user via SMS, then the user inputs it into the login system. In this sense, the server sends a code to the user then makes sure that it receives back the same password the user received.
3. The third method of one-time password generation is with a smartphone application such as Google Authenticator or Authy. After a user downloads the smart phone application, they enable two-step verification on their account and receive the secret key by scanning a QR code. In this setup, the user’s phone calculates the one-time password every time that they try to sign in.
1. Sign in to your account as you normally do, and go to your Dashboard> go to Configuration.
2. Go to your System Settings drop down menu, select Account. When your account appears, click on your account name. This will bring up the page seen below, click Enable next to Two-step verification.
3. Whenever you sign in to your account, you’ll need to enter both your password and a security code from your mobile device. Decide which method you prefer, SMS or mobile app. Security codes will be generated and sent to your chosed delivery method. Follow the instructions.
