Hi there @betien,

You define the login details in Step 7, when you run the following command:

bench new-site your_domain --admin-password 'erpnext_admin_password' --mariadb-root-username sammy --mariadb-root-password 'mariadb_password'

• bench new-site creates a new site based on the Frappe Framework.
• your_domain is the name for the new site. Make sure that your domain’s DNS has an A record pointing at your server’s IP.
• erpnext_admin_password is the desired password for ERPNext’s Administrator user. Keep this password in a safe place—you will need it shortly.
• mariadb_password is the password that you created at the beginning of the guide for the MariaDB user sammy.

Hope that this helps!
Regards,
Bobby
