If you use the same account for other campus services besides LON-CAPA, (e.g., e-mail, course registration, etc.), a separate centrally managed mechanism likely exists to reset a password. However, if your account is used for just LON-CAPA access you will probably be able to reset a password from this page.
Three conditions must be met:
An e-mail address must have previously been associated with your LON-CAPA username.
You must be able to access e-mail sent to that address.
Your LON-CAPA account must be of a type for which LON-CAPA can reset a password.
