Hi@akhtar,

You can set password to your cassandra account.

Follow the below given steps.

• Open the cassandra.yaml file.
• Replace the below lines.

authenticator value is 'AllowAllAuthenticator'. Change this authenticator value from 'AllowAllAuthenticator' to 'com.datastax.bdp.cassandra.auth.PasswordAuthenticator'. 

authorizer value will be 'AllowAllAuthorizor'. Change this authorizer value from 'AllowAllAuthorizor' to 'com.datastax.bdp.cassandra.auth.CassandraAuthorizor'.

• Login with username and password as cassandra.

$ cqlsh -3 localhost -u cassandra -p cassandra

• Change your password.

$ alter user cassandra with password 'newpassword';

Hope this will work.
Thank You
