Almost any setting can be changed by your own account through the web interface, as long as your account has ‘admin’ rights.
AFAIK, they only way to do so, is you’d need to go through the account creation process and use any email address. Again as an admin account for the site, you can go pull up the user in the admin tools and manually override their email verification (for example in the case you used a fake email address).
