Agents can manage their own profile in Settings or by expanding the profile menu on the top right and click Edit Profile.
Admins can manage the settings for their users in Admin > Users: Edit, or by going to the User Detail tab and selecting the user from the drop-down menu on the right.
Please note, usernames cannot be changed.
If a user forgets their password, they can request a reset link from the login screen, or an Admin can click [Reset Password] to request it for them. The password reset link will be sent to the user's email address.
