Hi
probably too late but you should create a new account for new user of laptop/PC and leave new account with no password.
consider if it should be an admin or restricted account.
If using computer for work purposes unless no confidential work related data on laptop there should be a password for all accounts
In Europe (if in Business or Government) there is any personal data relating to customers, employees etc you must protect that data from unauthorised disclosure
(account password may not be enough and encryption may be required)
