`clickhouse-client --host abc003
ClickHouse client version 22.8.2.11 (official build).
Connecting to abc003:9000 as user default.

If you have installed ClickHouse and forgot password you can reset it in the configuration file.
The password for default user is typically located at /etc/clickhouse-server/users.d/default-password.xml
and deleting this file will reset the password.
See also /etc/clickhouse-server/users.xml on the server where ClickHouse is installed.
