Name / identity of the client (IOS or Android phone)

null@example.com (Günni) — Fri, 05 Jul 2019 14:53:22 +0000

For a security-sensitive application, I would like to query which cell phone has just logged in to the Arduino via Blutooth. Only if this mobile phone is authorized should certain functions be released.
Does the remotexy library provide a system variable that contains the identity of the particular mobile phone?
Or is there another option?

Many thanks for the help.
