What is the default system administrator password for my NAS?

Introduction

All NAS devices have the default system administrator account "admin". This "admin" account can configure settings, create users, and install applications. This account cannot be deleted and depending on your QTS/QuTS hero version may be disabled by default. To protect your system from malicious attacks, it is recommended to create a new administrator account and disable the "admin" account. A new administrator account can perform the same actions as the "admin" account and helps keep your device secure.

To comply with the EU’s cybersecurity requirements, manufacturers must avoid universal default credentials. Corresponding EU/industry standards require no universal default passwords, mandating unique per-device credentials or enforcing a password change on first use. Accordingly, starting with QTS/QuTS hero 5.2.0, the default administrator password was changed to the device’s Cloud Key (earlier versions used the first NIC’s MAC; much older versions used admin/admin), aligning with these requirements.
