A Community Leader can set the access levels for the community using the Community Administration.
- Click the Community Settings tab in the Community Administration. 
- Click Community Access in the side navigation bar. 
- Select one security level from the Basic Access page and click Update. 
The following access levels are available:
| Allow anyone, including Unregistered Users | This is the most open level of security. Any visitor can view the community pages without registering or logging in. | 
| Allow all Registered Users | This setting requires that users register before viewing the community pages. There are no restrictions on who can or cannot register. | 
| Allow Community Guests, Members, and Leaders | This setting requires that the visitor have a defined role within the community, but places no restriction on what the community role must be. | 
| Allow Community Members and Leaders | This setting requires that the visitor have Community Member or Community Leader status. | 
| Allow Community Leaders only | This setting is the most restrictive level of community-based security. Only Community Leaders and Portal Administrators have access to the community. |
