requested review from @gajesh24

marked this merge request as ready

Comment 1: The authorization part works great (no problems logging in or out).

Comment 2: Did you test the functionality of the tasks? Doesn't work for me. So I checked mongosh, and see that the user is creating successfully, but tasks are not being created.

merged
