Please contact Native Ads support for assistance or with any questions relating to your account information. Unfortunately the Username cannot be changed once a publisher has registered. However a publisher can change their password from the My Profile page under the My Account menu in the publisher system.
Please contact the Native Ads support team if any difficulties arise when trying to change account settings and a Native Ads rep will be in touch shortly to resolve the issue. Alternatively, if you have spoken previously or been assigned to an account manager, reach out to them directly with any questions or concerns.
