With at.js the lifetime of at.js 2, mbox cookie lifetime is now 2 years. The help doc https://docs.adobe.com/content/help/en/core-services/interface/ec-cookies/cookies-target.html tells that cookie duration is not configurable.
Also there is no impact on the Visitor profile lifetime, so if the value of visitor profile lifetime is set for 14 days for the  account then it would expire if the visitor doesn't come back to the website within 14 days. So would like to know what is the relevance of the setting mbox cookie duration to 2 years.

Thank you.

The user profile is stored up to 90 days. If the visitor comes back on the 91st day, the target id for the user would be the same, but we would consider the user as a new visitor. The cookie duration set to 2 years is arbitrary in that it doesn't impact the user profile. The duration is a standard seen in Experience Cloud cookies.
