i think should we have password and user name even for individual use this will be much useful , especially when others use your P.C.
Desktop edition is meant for individual use. you can lock the program with a third-party software if others use your PC.
you can always upgrade to Cloud or Server editions for this feature.
actually i don’t know what you mean with third-party software
you can google to find software which would let you password protect applications and folders.
