-:::tip
-
-**Create new users**. The `root` user only works when you access Databend from localhost. You will need to create new users and grant proper privileges first to connect to Databend remotely. For example,
-
-```sql
--- Create a user named "eric" with the password "databend"
-CREATE USER eric IDENTIFIED BY 'databend';

-GRANT ALL ON default.* TO eric;
