1. A computer-based method of authenticating chatbot users and recovering chat history associated with the chatbot users, the method comprising:
recording a first chat conversation between a first chat service operator and a first user, wherein the first chat conversation includes a first-step authentication and a chat history;
detecting a request to resume the first chat conversation, wherein the detected request to resume the first chat conversation is detected on a different platform from a first platform on which the chat service operator hosted the first conversation;
in response to detecting the request to resume the first chat conversation, initiating a recovery process by sending a random-generated token to the first-step authentication;
receiving verification of the random-generated token;
generating, by a large language model, one or more authentication questions based on content of the chat history;
authenticating the first user based on one or more correct answers to the one or more authentication questions; and
resuming the first chat conversation with the authenticated first user, the resumed first chat conversation including the chat history.
