Handle needed for laptop? (8)
I believe the answer is:
username
'handle' is the definition.
(I know that handle can be written as username)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for username that I've seen before include "Something needed for logging in" , "Electronic identity" , "Computer log-in requirement" , "Login ID" , "Person's computer ID" .)
