Manage Event Password
Event Passwords are a good way to control who can see a stream. If you have a private event or an event that you need to limit the audience for a password can be added before, during or after the event.
To add a password to a single event, use the event editor’s newly included password section:

Password option within the Event Editor
To add passwords in bulk, use the Manage Event Password Page on admin.stretchlive.com. This tool can only apply passwords, it does not remove them. In the case where a password exists it will replace the password and the Required on Event Type (Live, On Demand or Both) that currently exists.
