Large-scale multi-terminal access authentication method and device, computer equipment and medium

The invention relates to a large-scale multi-terminal access authentication method and device, computer equipment and a medium, and the method comprises the steps: obtaining an authentication request sent by a terminal; analyzing the authentication request, and obtaining a communication protocol identifier, a terminal type identifier and user demand data corresponding to the authentication request; inputting the terminal type identifier and the user demand data into a preset machine learning model, and determining a target authentication protocol matched with the authentication request in combination with an output result of the preset machine learning model and the communication protocol identifier; converting the authentication request into a protocol format corresponding to the target authentication protocol to obtain format conversion data; and performing access authentication on the format conversion data based on an authentication source corresponding to the target authentication protocol.
