You could use some md5-hashing to make it more secure.
warn message = X-Authenticated-As: $authenticated_id \
(${md5:Secret$authenticated_id})
authenticated = *
This will allow you to check the value later, if needed.
or you add two headers, like
warn message = X-Authenticated-As: $authenticated_id \n\
X-Authenticated-As-Hash: ${md5:Secret$authenticated_id}
authenticated = *
this will make the check itself a bit easier.
