Sys User

The database has a special user SYS that cannot be deleted. The SYS user has universal privileges and can perform all actions on the database.

The default password of the SYS user is exasol. To change the SYS user password you must be logged in as SYS or as a user with the ALTER USER privilege:

ALTER USER sys IDENTIFIED BY "<new_password>";

To prevent a security risk, always change the default password of the SYS user to a secure password.
