Non-networking system dynamic password generation method and non-networking system identity authentication method

The embodiment of the invention discloses a non-networking system dynamic password generation method and a non-networking system identity authentication method. The non-networking system comprises an operation end device and a remote end device. The non-networking system dynamic password generation method comprises the following steps: an operation end device generates an authorization code and an authorization password according to a current date and current time, stores the authorization code and the authorization password, and displays the authorization code; the remote end equipment generates a login password according to the authorization code, the current time and the authorization duration, and displays the login password; or the remote end equipment generates the login password according to the current time and the authorization duration, and displays the login password. According to the scheme, the randomness, the dynamism, the non-repeatability and the better concealment of the generated authorizati
