What is the purpose of AMCVS_?
The AMCVS_ cookie is set by the Adobe Experience Cloud Identity Service (ECID) alongside the persistent AMCV_ cookie. It operates as a session flag to indicate that a user's browser session has successfully initialized; per Adobe's documentation its value is always 1 and it discontinues when the session has ended. Its name format includes a dynamic organization ID (e.g., AMCVS_####@AdobeOrg), ensuring that the session is tied to the specific Adobe Experience Cloud tenant tracking the site.
By maintaining this session state, the cookie allows various Adobe solutions (such as Adobe Analytics, Adobe Target, and Adobe Audience Manager) to accurately identify and group a visitor's page views and interactions into a continuous session. Once the browser session ends, the AMCVS_ cookie expires, signaling the conclusion of that session for tracking and analytical purposes.
What are the Privacy Risks of AMCVS_?
Risk Level: Medium
The AMCVS_ cookie is categorized as Medium risk because it functions as an essential component of the Adobe Experience Cloud's visitor tracking system. Although its stored value is simply a static flag (typically "1") indicating an active session, it operates in tandem with the AMCV_ cookie to link a user's activities to a persistent pseudonymous identifier. This facilitates cross-session behavioral profiling, analytics, and personalization.
How to Remove AMCVS_ from a Website
To remove the AMCVS_ cookie, a website administrator must remove the Adobe Experience Cloud Identity Service (ECID) script (typically VisitorAPI.js or the Adobe Experience Platform Web SDK) from the website's source code. This involves removing or disabling the corresponding tags within the site's Tag Management System (such as Adobe Launch, Adobe DTM, or Tealium iQ). Because this cookie is a fundamental requirement for tracking session initialization across Adobe Experience Cloud products (like Adobe Analytics and Adobe Target), it cannot be selectively disabled while keeping those solutions fully functional. Completely removing the cookie requires discontinuing the use of the overarching Adobe Identity service.
