Shrivatsa, to get your JEE Mains results, you need to enter your application number, date of birth and security pin.

Now just below the textfield where you are supposed to enter the security pin, you can find a rectangular box with 6 alphanumeric characters written in red. You need to type in the same characters in the security pin column. The characters are case sensitive so please assure that you are entering it in the right case.

The security pin is same as the captcha that you might find on any other websites to ensure that you are not a robot but a legitimate human user. Hope it helps.
