Marketplace Delete Button

Recently I wanted to start a new marketplace since I was mainly testing with my first one and wanted to have a different name, subdomain, commission etc. There wasn't an easy delete button as you would expect, I had to contact support and supply them with my marketplace subdomain and login ID. After this the support person said that the request would be passed onto the back-end development team who would complete the process.

The big issue: All I had to do was sign up for a support account (very easy to do) and give them my subdomain (publicly available to anyone who visits my marketplace) and my login ID (the hardest thing to find but could be obvious if people just used their email or used the same username as their subdomain). This got me a little bit worried that someone could delete my entire marketplace that easily so I thought it would be a better decision to implement a delete button for marketplaces so that I actually have to login with my username and password to delete it. It also might be smart to have a confirmation code/link sent to the email just to confirm this.
