The invention discloses a soft lock permission updating method and device, relates to the technical field of encryption, and aims to realize a convenient and safe soft lock permission updating function. The method comprises the following steps: receiving a query request which is sent by a software developer and is used for querying terminal equipment under a target software user directory; based on the query request, sending a corresponding terminal equipment list under the target software user directory to a software developer, so that the software developer generates soft lock permission upgrading files of part or all of terminal equipment in the terminal equipment list; and receiving a soft lock permission upgrade file generated by the software developer, generating a soft lock permission upgrade installation package based on the corresponding terminal device hardware fingerprint information, and providing the soft lock permission upgrade installation package to the corresponding terminal device. The method and the device are suitable for updating the soft lock permission of the soft lock.
