Your client having a hard time logging in? Go ahead and change their password for them. No worries, they can always change it to something else once they've logged in.
To change your clients password, start by clicking the Clients button in the bottom left hand portion of your screen. (See image below.)
Next, click on the client you would like to change the password for.
After this, click the blue Change Password button. After you have entered the new password that you would like your client to have, click OK.
