If you are coming to this page for the first time, you need to create an account. For that, use Create an account link. A new pop-up will open, which will ask for your phone number, and you will also be asked to create a new password. Remember the password, because you will be using it to login to your account in the future. Generate OTP and input it to create your account.
After creating your account once, login from this page only – don’t go to Create an account again!
