How can I password protect my marketplace until I'm ready to make it public?

Securing your Marketplace with a username and Password

Admins typically gate access to the marketplace while they’re preparing for launch and make it publicly accessible when they are ready to go live. 

Marketplace Managers can do this by:

1. Manage Marketplace > Settings > Marketplace Functionality > Enable Password Protected Marketplace. 
2. Create a username and password and  document it somewhere safe. Scroll to bottom andSave Settings.
3. When enabled, all users are prompted to enter a username and password provided by the Marketplace Manager before viewing any page on the marketplace.
4. When you're ready to go live, disable this feature.
