Third-party cookies and Personalization¶
Personalization creates first-party cookies by default, using the domain of the website the visitor is viewing. Third-party cookies are optional in Personalization, and if enabled, use the acquia.com domain.
Third-party cookies are useful if you maintain several websites using different domain names, and want to track users across all your domains. Some browsers may prevent the creation of third-party cookies or limit their life span. For example, browsers using Webkit’s Intelligent Tracking Prevention, such as Safari, will delete cookies and browsing data if a website visitor has not interacted with your website in 30 days.
Security concerns from cookies¶
The cookies set by Acquia Personalization neither contain sensitive information nor provide any access on the server-side. Unlike traditional authentication cookies, Personalization cookies are only used for tracking purposes and do not provide access to any application. Therefore, they do not pose any security concerns.
