({{, (RefLink[$WolframUUID, paclet:ref/$WolframUUID]) 
gives the Wolfram UUID of a currently logged-in user, or the user who owns a cloud object containing the code used for the current evaluation.}})

OpenersNotesSection(Spacer1)Details

(RefLink[$WolframUUID, paclet:ref/$WolframUUID]) returns the Wolfram UUID relative to your current (RefLink[$CloudBase, paclet:ref/$CloudBase]).

Since every cloud object must have an owner, there is always a definite value for (RefLink[$WolframUUID, paclet:ref/$WolframUUID]) for any evaluation occurring in the cloud.

(RefLink[$WolframUUID, paclet:ref/$WolframUUID]) may differ from (RefLink[$RequesterWolframUUID, paclet:ref/$RequesterWolframUUID]).

For a desktop system not authenticated against the cloud, (RefLink[$WolframUUID, paclet:ref/$WolframUUID]) is (RefLink[None, paclet:ref/None]).

A Wolfram UUID is a unique permanent identifier associated with a user.
