Yes! You can protect your site using the Lock block.
In order to add it to your site, please follow these steps:
- Log into your Impress.ly account.
- Click on the 'Add more content' button.
- Click on the Business tab.
- Click on 'Lock' and Add. Enter the password with which the site will be protected.
- Drag the Lock block above the content blocks that you'd like to protect with a password. Make sure the content you want to protect is nested under the Lock block (as you would nest content under a Submenu block).
