+# Configure Cookie Consent Banner
+
+The Cookie Consent Banner feature allows you to control the visibility of cookie consent notifications across different applications in WSO2 Identity Server.
+
+## Overview
+
+You can configure the cookie consent banner at different levels:
+
+-   **Global level**: Controls the banner across all applications.
+-   **Application-specific level**: Controls the banner for specific applications (Console and MyAccount).
+
+??? Note "Affected Applications"
+    These configurations do not affect the authentication or recovery portals. Instead, they only determine whether the banner is shown within the respective applications.
+
+## Configuration
+
+All configurations are made in the `deployment.toml` file located in `<IS_HOME>/repository/conf/`.
+
+### Global Configuration
+
+To enable or disable the cookie consent banner globally across all applications, add the following configuration:
+
+```toml
+[ui.cookie_consent_banner]
+enabled = true # Set to 'false' to disable globally
+```
+
+By default, this is set to `true`.
+
+### Console Application Configuration
+
+To enable or disable the cookie consent banner specifically for the Console application:
+
+```toml
+[console.ui]
+is_cookie_consent_banner_enabled = false # Set to 'true' to enable for Console
+```
+
+### MyAccount Application Configuration
+
+To enable or disable the cookie consent banner specifically for the MyAccount application:
+
+```toml
+[myaccount.ui]
+is_cookie_consent_banner_enabled = false # Set to 'true' to enable for MyAccount
+```
+
+### Configuration Priority
+
+Application-specific configurations take precedence over global configurations. For example:
+
+*   If global is disabled but Console is enabled, the banner will **show** in Console.
+*   If global is enabled but MyAccount is disabled, the banner will **not show** in MyAccount.
