The system passphrase is used to protect sensitive information stored on all Niagara systems, and on the SD card in JACE-8000 controllers. The system passphrase is assigned as the file passphrase for “portable” files, such as backups and station copies, and is used to encrypt those files. During operations in which you transfer encrypted files to a system (restoring backups, transferring a station, etc.) you are prompted to supply the file passphrase if it doesn’t match the system passphrase. The system passphrase defaults to the factory default platform password. During commissioning, you will be prompted to change the default system passphrase. You must remember the system password and keep it safe. If you lose the system passphrase, you will lose access to encrypted data. To change the system passphrase, use the Platform Administration tool. For more detailed information, see “System passphrase” in the Niagara Platform Guide.
