The admin user account is the default administrator account. It can configure settings, create users, and install applications. You cannot delete this account. To prevent malicious actors from compromising your system due to easy passwords, QNAP strongly recommends changing the default admin password, creating another administrator account or logging in with an existing admin account, and disabling the default admin account. A new administrator account can perform the same actions as the default administrator account.

The default admin account must be enabled in two specific scenarios: when you need to access the QNAP turbo NAS via Secure Shell (SSH) or Telnet and when you need to access Console Management.

The default password of the admin account is the MAC address of Adapter 1. If the system detects that you still use this default password when you log in with the admin account, you will be asked to change your password to enhance your account security.
