cmMaintCmdPassword is a read-write display string setting the FTP password paired with cmMaintCmdUserName for maintenance-command file transfers, always read back as '****' for security and required by the description to start with an alphanumeric character, and it's ignored for bulkCPEDownload. An administrator sets this once to match the target file server's account credentials. For example, after changing the backup FTP account's password, the operator would update cmMaintCmdPassword to match, then verify with an actual configBackup run since the readback will only ever show asterisks.
