The present invention relates to a method, a device and a system for user authentication on a PON. The method includes the following steps: an OLT receives a user authentication request initiated by an ONU, which carries a password ID; the OLT authenticates according to the user password ID reported by the ONU, and opens or closes a channel from the ONU to the network side according to the authentication result. The invention further discloses a PON and an OLT. According to the method for user authentication in the invention, user management and maintenance of PON may be easier and simpler, and terminal interchangeability and user security may be improved; moreover, after a user changes the ONU, the new ONU may also access the network using the password ID.
