Password for man entering bishopric (6)
I believe the answer is:
sesame
'password' is the definition.
(I've seen this before)
'man entering bishopric' is the wordplay.
'man' becomes 'sam' (**).
'entering' means one lot of letters goes inside another.
'bishopric' becomes 'see' (I've seen this before).
'sam' going within 'see' is 'SESAME'.
'for' is the link.
(Other definitions for sesame that I've seen before include "Seed or oil used in cooking" , "Plant yielding seeds used for flavouring bread" , "Open . . . . . . cries the magician" , "Seeds producing an edible oil" , "Open ...... is magic phrase for obtaining access" .)
