1. Specify your custom NuGet feed URL’s in the solution’s nuget.config file. Do not store any usernames & passwords in this file.

2. Create username & password variables in your build definition in VSTS. Variables can be encrypted and will not be displayed in any of the build log outputs. Here I'll create MyCompanyNugetUser and MyCompanyNugetPwd variables.

3. In our build steps, we add a Powershell script as the first action, this will read the username & password variables and update the user level nuget.config file on the build machine. Below is the code snippet from my inline Powershell script:

   Arguments:

   $(MyCompanyNugetUser) $(MyCompanyNugetPwd)
   

   Script:

   param($user, $pwd)
   
   $nugetFile = "$ENV:AGENT_HOMEDIRECTORY\agent\worker\tools\nuget.exe"
   Write-Output "Looking for nuget.exe in $nugetFile"
   
   if (-not (Test-Path $nugetFile))
   {
     Write-Error "nuget.exe could not be located."
     return
   }
   
   Write-Output "nuget.exe located"
   
   $cmd = "$nugetFile sources add -name MyCompany -source https://nuget.mycompany.com:443/nuget -username $user -password $pwd -StorePasswordInClearText"
   Write-Output $cmd
   iex $cmd
   

4. Next, we just continue to execute the default NuGet Restore step from Microsoft’s templates
