To keep your mural extra private, you can protect it with a password. You'll find this option under the Visitors tab when you share a mural.
Here’s how to password protect your murals:
1. Click the pink Share button in the upper right-hand corner of the canvas.
2. Select the Visitor link tab in the modal window.
3. In the bottom left corner of the modal, click Add a password.
Now you can have greater control over visitors accessing your shared murals.
