It's about what the secretary will do to confirm a password
I believe the answer is:
retype
'the secretary will do to confirm a password' is the definition.
I can't judge whether this defines the answer.
'it's about what' is the wordplay.
'it's about' becomes 're' (regarding).
'what' becomes 'type' (I can't explain this - if you can you should believe this answer much more).
're'+'type'='RETYPE'
Can you help me to learn more?
(Other definitions for retype that I've seen before include "Produce amended" , "made to revise earlier draft perhaps" , "Put into printed characters again" , "impress again" , "Set (the same text) again on a word processor" .)
