To reset your password, you only need to click on your initials up the top right-hand side of the tool, and then click 'Edit Profile' as shown just below your workspace name.
A pop-up window will appear which will contain all of your profile information. On the same pop-up, just below your login name, you will see the button to reset your password.
Note that this will send you an email that will contain a link; clicking this link will take you to a new password entry/confirmation screen.
If instead of your own password, you would like to reset the password of another staff member, the process is just as easy! Go to the Staff page, as seen in your navigation bar, and then find the staff member on this list. Click on their name, and this will open a similar profile screen. Click the 'Send Login Details' button as seen on the top right-hand side:
This will send a similar set password email as the first process.
