You will need to login into your account. Once this is done, please click on "Download Skype Plugin".
Select the version that you need, the one for Windows or the one for Mac.
The plugin will start downloading. After the download is complete, please click on it.
A pop-up will appear where you must click "Install".
Before the plugin is installed, Skype and the plugin will ask you to Approve or Deny the plugin's access to Skype. You will need to approve it. This will happen if you are logged in Skype. If you are not logged in, you will need to login.
After doing so, the final step will be to login the plugin.
If your Skyprivate Username matches your Skype one everything will be fine and you will appear as logged in.
Attention! check both your Skype and Skyprivate username. They need to match in order to appear as logged in.
