$RequesterWolframID
✖
$RequesterWolframID
gives the Wolfram ID of an authenticated user requesting the current evaluation.
Details

- If the current evaluation was not initiated by an authenticated user, $RequesterWolframID is None. This can occur, for example, if a desktop user has not authenticated against the cloud, or a cloud service not requiring authentication is being used.
- A Wolfram ID is normally an email address. Unlike a Wolfram UUID, a user may be able to change it.
