You can protect the course against unauthorized use with a watermark that will appear on the slides, as well as using a password and time or domain restrictions.
To go to the security settings:
You can use an image from your computer as a watermark, and adjust its transparency and position on the slide. In addition, you can specify a link to a web page that will be opened by clicking on the watermark.
A password protects your course from unauthorized viewing. To view the course, the user will need to enter the password.
Please note that the password is stored in the course in encrypted form. It can not be restored if you forget your password.
Users' ability to view the course can be limited by date. In this case, slides are only available in the specified time interval (before the date, after the date, between the dates).
To add a time limit:
You can specify values in both fields at once to limit the time period in which the presentation will be available for viewing.
Allow users to view the course only from certain domains and their subdomains. The course can not be viewed on a local computer or another website. Use this option to protect the content from unauthorized distribution.
This option does not limit playback if you insert a course on a page on another domain using the HTML <object> tag.
