The invention relates to a password authentication method, equipment and system. The method comprises the steps that a challenge code for a user account is set based on a first graph matrix generated through a server; the challenge code is sent to the server, so that whether the challenge code smoothly exists in a password generated through the server for the user account or not is judged. Through the method, even though the challenge code utilized this time is acquired by a listener and the like, a real password cannot be restored, and therefore the security of the user account can be ensured reliably. In addition, when the service based on the password authentication technology is provided for oversea users, the security of user accounts of the oversea users can be ensured. |
