You cannot view other user's passwords. However you can change user's passwords by going into the "Set Up Users" module.
In the "Set Up Users" module click the edit icon to the left of the applicant you wish to change passwords for. On this screen check the box "Assign Password Manually?".
A new text box titled "Password" will appear, remove the old contents of that field and enter the new password you would like to set for the user and hit "Save & Exit".
