Users can reset their own passwords by clicking on the ‘Forgot Password’ link present on the login page. Alternately, an admin can also do this by following the below steps:
In order to reset the password of an existing user you can:
Click “Users” from the navigation bar and select “Manage Users"
Clicking "Manage Users" will show a list of users with a "View" button next to it.
Click on the "View option" against the user profile for which the password has to be reset.
Once done,
Click on “Tools” located on the top-right hand side corner of your screen
Select “Reset Password” in the pop-up.
Confirm “Reset” in the pop-up that appears and the password will get reset to ‘password’.
