ALTER USER
Alter existing user options.
Alter existing user options.
Note:
ALTER USER is supported
for backwards compatibility. Authentication and authorization for Cassandra 2.2 and later
are based on ROLES.Superusers can change a user's password or superuser status. To prevent disabling all
superusers, superusers cannot change their own superuser status. Ordinary users can change
only their own password. Enclose the user name in single quotation marks if it contains
non-alphanumeric characters. Enclose the password in single quotation marks. See CREATE ROLE for more information about
SUPERUSER and NOSUPERUSER.
