To create a private session protected by a password, these are the steps to must follow:
Login to your Bkool account at BKOOL.com> Sessions. Once the session you want to do with your colleagues is located, click on Configure, this option appears when you put the cursor over it. Later, in the details section (top right) you will see the password option.
You must share with your colleagues the session name, the password, and the day and time at which you will start the session, so that they can find it. They need to access to the simulator, click Search> Routes> Filter by private sessions. Once the search has been carried out, all the private sessions started at that moment will appear.
Once the have selected the session, they can enter the password next to the red padlock, that appears when the session opens.
In this way you can compete with your colleagues, without anyone else joining the session.
