[New] Passcode is needed for download for the first time

To improve the service quality, we introduced a passcode confirmation when you download the OBIS-SEAMAP data first time.

When you download the OBIS-SEAMAP data, you fill in the download form with your contact information. To make the contact information more accurate, for the first-time user, an email with a passcode will be sent to the email address provided so as to make sure the email address is correct. The email will usually reach you within a few minutes and you need to enter the passcode into the form. This is an one-time action. From the second time on, you don't need to enter passcode as we know your email address is correct.

Thank you very much for your understanding of this change.
