Security of your account is very crucial as it helps us to keep our account protected from the hackers. To enhance the security of your account, Yahoo provides an important feature known as "Second sign in verification". This feature adds an extra layer of security for its users. Yahoo Customer care Australia is providing their users with the steps to enable the 2-step verification process in your account. 1. Open your Yahoo account. 2. In the home page of your account, click on the "mail" icon present at the top left corner in purple banner. 3. Now, search for the gear icon on the right side of your screen. Click on that icon and drop down menu will appear. Select "Settings" in that menu. 4. A new list of settings will appear in which your Yahoo email address will be present at the top middle. Below the email address, three links will be present. 5. From these three links choose "Edit your account info". After that a new window will appear and you have to provide your password again for security reasons. 6. Enter your password and click on the Sign in button. 7. Here, choose "Set up your second sign-in verification" and click on "Get started". 8. Now, you have to enter your mobile phone number. First, select your country and in the next box enter your phone number. 9. Click on the send code button to continue. 10. Finally, enter the verification code in the screen which appeared in your mobile number. This will be a 5 digit code. After entering click "Okay". After following these steps, you will be able to add an extra security to your account.
