You can enable anonymous access (also known as public access) to your Confluence site by granting the 'Use Confluence' permission  to 'anonymous' users. An 'anonymous' user is someone who has not logged in to the Confluence site. The 'Use Confluence' permission is also called 'can use'.

This user category gives you an easy way to administer users who have not logged into the site. Permissions assigned to this category apply to all anonymous users of the site.

Enabling anonymous access to the site

If you want to make your site visible to everyone, including people who have not logged in, you must enable anonymous access at site level.

To enable anonymous access to your site:

1. 
2. Choose Global Permissions in the left-hand panel.
3. Choose Edit Permissions.
4. In the 'Anonymous Access' section, select the can use check box to enable anonymous access to the content on your site.
5. If you want to allow anonymous users to see user profiles, select the check box in the View User Profiles section.
   Note: You must grant the 'can use' permission as well, if you want to grant the 'View User Profiles' permission.
6. Choose Save All.
