The invention relates to an access method and device, an electronic device and a storage medium. The access method comprises: receiving an access request of a terminal, and the access request comprising terminal information and user information of the terminal; generating a terminal identifier corresponding to the access request according to the access request; querying the state information of the terminal identifier to obtain a query result; and sending an access feedback message to the terminal according to the query result to realize access of the terminal. According to the embodiment of the invention, the access request of the terminal containing the terminal information and the user information can be obtained through the process, the unique terminal identifier fusing the terminal information and the user information is generated. The access of the terminal is realized based on the terminal identifier, the security is ensured, the method can be applied to a public cloud environment and a private cloud environment, the application range is wide, the automation degree of the access process is high, and the realization is convenient.
