Database users 

How to create and work with users.

User-based access control enables authorization management on a per-user basis.
Note: Creating users is supported for backwards compatibility. Authentication and authorization are based on roles, and role-based commands should be used.

Procedure

  • Create a user with a password. IF NOT EXISTS is included to ensure a previous user definition is not overwritten.
    cqlsh> CREATE USER IF NOT EXISTS sandy WITH PASSWORD 'Ride2Win@' NOSUPERUSER;
  • Create a user with SUPERUSER privileges. SUPERUSER grants the ability to create users and roles unconditionally.
    cqlsh> CREATE USER chuck WITH PASSWORD 'Always1st$' SUPERUSER;
    Note: WITH PASSWORD implicitly specifies LOGIN.
  • Alter a user to change options. A role with SUPERUSER status can alter the SUPERUSER status of another user, but not the user currently held. To modify properties of a user, the user must have permission.
    cqlsh> ALTER USER sandy SUPERUSER;
  • List the users.
    cqlsh> LIST USERS;


  • Drop user that is not a current user. User must be a SUPERUSER.
    DROP USER IF EXISTS chuck;
