+# Proposal: `Enable / Disable Anonymous Access`
+
+Author: `Ye Liu / cafeliker`
+
+Discussion: `https://github.com/goharbor/harbor/issues/10760`
+
+## Abstract
+
+Add the system configuration to enable / disable anonymous access
+
+## Background
+
+Anonymous access is good for community purpose; and for Enterprise, the public repo should be only visible for authenticated people to protect the content and IP.
+
+It's a required feature to allow administrator enable / disable the anonymous access
+
+## Proposal
+
+Add a configuration item named "Disable anonymous access" in the System Setting page with a checkbox:
+1. When "Disable anonymous access" is checked, non authenticated users can't access any resources include the public project in the Harbor instance;
+2. When "Disable anonymous access" is unchecked, keep the existing behavior that any user can query the public project and pull docker images under a public project without login.
+
+## Implementation
+
+1. Add the new "Disable anonymous access" checkbox into the system-settings.component.html file under the portal package
+2. The docker pull / push permission can be controlled through the rbac package
+3. Add the anonymous access check login in the List() method on project.go under the core/api package.
