You can password protect your chat room.
To protect your chat room with a password, enter the chat rooms customization page:
Click on the Customize room link
In addition to the password protection, there are 2 states of permission you can preset for your chat room:
A.) Wide Open - Anyone can enter your chat room
In that state, you can select to be notified when someone enters your room or not.
B.) Restricted – No one can enter the chat room unless you confirm. In that state, you must be logged in to ooVoo to allow others to enter your chat room
From this page you can also customize widgets and get the code to embed on your web site.
