      Signup Code blocks visitors from registering a new site or user account without providing a custom, network specific, signup code.

      Add a simple, effective layer of protection and ensure only specific people can create new users or sites. Designed to compliment any Multisite configuration and work flawlessly with other third-party plugins.

      Configuration is fast…really fast

      Set a signup code and your new protection wall will automatically be added to the network signup page. The simplicity makes it easy to set, reset or change your code frequently; all while enhancing security.
