Menace is friendly, accepting identification (10)
I believe the answer is:
intimidate
'menace' is the definition.
(thesaurus)
'friendly accepting identification' is the wordplay.
'friendly' becomes 'intimate' (I've seen this before).
'accepting' is an insertion indicator (inserted letters are accepted).
'identification' becomes 'ID' (abbreviation).
'intimate' placed around 'id' is 'INTIMIDATE'.
'is' is the link.
(Other definitions for intimidate that I've seen before include "Strike fear into" , "Bully" , "Threaten" , "Cow" , "Scare" .)
