Adding a support pin can be very helpful, for example, it's the easiest way for us to verify that you own the account. This can also help you save time and even help you get out of a bind. If you lost your password and the email on file is no longer active, having your support pin can help us verify your account and get you the new login details fast. Without the support pin, we have to verify a lot of personal details, which takes time and can seem intrusive.
We don't want to use your time or get any of your details, but without a support pin we have to be sure you are the owner before we can give any secure information or make changes on the account. This is to make sure your account is safe, which is our number one priority.
