Relief only after securing account (6)
I believe the answer is:
solace
'relief' is the definition.
(solace is a kind of relief)
'only after securing account' is the wordplay.
I cannot really see how this works, but
'account' could be 'ac' (abbreviation) and 'ac' is present in the answer.
'only' could be 'sole' (synonyms) and 'sole' is found in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for solace that I've seen before include "Something that comforts distress" , "amusement" , "Comfort in time of disappointment or sorrow" , "Comfort at a time of sadness" , "Comfort in time of distress" .)
