title: How to add a password protected repository to Sonatype Nexus?
body: <p>We're using Sonatype Nexus to manage different repositoryies. There's a request to add a password-protected repository to our "Public Repositories" group. The problem is, I don't really know how to accomplish this.</p>
  
  <p>I can create a new repo and add it to the existing group, and there's the option for authentication, but how can I be sure to be doing this right? Searching the net only yields results for CREATING a protected repository, but nothing about adding an existing, password-protected remote repository.</p>
  
  <p>If there are links to resources that explain how to tackle this particular problem, I would be thankful.</p>
