but the problem is that my registration of rajasthan counselling was done by someone else and he entered his own email and phone no. That is why i want to change the password so that anyone cannot misuse it

farheen qureshi This was coming the moment you gave someone the power to enter the details for you. Request the person who made the registration to give you the details so that you don't have to ask him everytime. Please do not give anyone such power henceforth. Otherwise such situations arise afterwards. Thanks.
