SPI_login is a SmartPlant Instrumentation database schema (database user) created only in SQL Server during the database setup. Each SPI_login schema stores the encrypted Admin schema password in the database. This schema login is shared for all databases you create in a particular SQL Server instance. For example, if you create SPI1 and SPI2 databases in the same instance, each database contains the SPI_login schema but, at the instance level, both schemas share the same login, whose name is SPI_login and password is spi_login_pwd (lower case). The login name is set permanently in the software. The System Administrator can change and encrypt the spi_login_pwd password if needed.
