In an information-processing device, a memory is configured to store setting information including an operation setting for the information-processing device. A controller is configured to perform: acquiring; determining; allowing; importing; and encrypting. The acquiring acquires import authentication information including a device password for the information-processing device while a removable storage medium storing import setting information is connected to an input-output interface. The determining determines whether the device password matches a preset device password of the information-processing device. The allowing allows, in response to determining that the device password matches the preset device password, the import setting information to be imported. The importing imports the import setting information from the removable storage medium into the memory as the setting information. The encrypting encrypts the import authentication information using the device password to create encrypted import authentication information and stores the encrypted import authentication information into the removable storage medium.
