Introduction
All NAS devices have the default system administrator account "admin". This 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.
The default password of the "admin" account varies depending on your QTS/QuTS hero versions. Please check your versions before proceeding.
If you still cannot log in to the NAS after trying the methods in this article, please post your question and provide relevant information on the QNAP Community Forum for further assistance.
Concepts
Understanding NAS Account & Cloud Key & QNAP Account
Tip
- We recommend understanding the differences between these three concepts before proceeding to steps.
- Whenever you log in to your NAS or to a QNAP service, please double-check the account type you are prompted to provide.
NAS Account: A NAS account is a local account on your QNAP NAS, used to log in to this specific device. "admin" is the NAS account created by default on every NAS. For QTS/QuTS hero 5.2.0 and later, this account is disabled by default and is automatically re-enabled after a system reset. This FAQ explains how to retrieve the password of this default "admin" NAS account. If you have created a different administrator account during device setup, the passwords described in this FAQ do not apply to that account.
Cloud Key: A Cloud Key is a unique identifier that comes with every QNAP NAS, regardless of whether you have configured any cloud settings. You can usually find the Cloud Key on a sticker on your device, in your Quick Installation Guide or in your device details on Qfinder Pro. For QTS/QuTS hero 5.2.0 and later, this Cloud Key serves as the default password for the "admin" NAS account. Outside of that specific use, do not treat your Cloud Key as a login credential.
QNAP Account (QNAP ID): A QNAP account (QNAP ID) is an account (typically your email address or phone number) used to access various QNAP services (such as myQNAPcloud) and to manage your NAS remotely. Your QNAP account and your NAS account are separate credentials with separate passwords.
Details
QTS/QuTS hero 5.2.0 and later (such as 5.2.x, 5.3.x, 6.0.0)
Note
- The default "admin" account is disabled by default but will be automatically enabled after a system reset or system restore. To protect your system from malicious attacks, we recommend creating a new administrator account and disable the default administrator account "admin".
- 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.
The credentials of the default administrator NAS account:
- Username: admin
- Password: The Cloud Key of your device in uppercase letters and without any special characters. For example, if the Cloud Key is Q1234-5678, the password is Q12345678
Finding your device's Cloud Key
You can find the Cloud Key of your device with any of the following methods:
Method A: From the device sticker or the Quick Installation Guide
You can find your Cloud Key from the sticker attached to the cover of your NAS or from the Quick Installation Guide that comes with your NAS.

Method B: Use Qfinder Pro
- Use Qfinder Pro without a NAS user account:
- Power off your NAS.
- Remove all hard drives from your NAS.
- Remove all internal M.2 SSDs and QM2 PCIe expansion card if any.
- Power on your NAS.
- Download and install Qfinder Pro.
- Open Qfinder Pro.
- Select your device.
- Click Details.
- The Device Details window appears.
Your device's Cloud Key is displayed in the Device Details window.

- Use Qfinder Pro with a NAS user account:
- Download and install Qfinder Pro.
- Open Qfinder Pro.
- Select your device.
- Click Details.
The Login window appears. Enter your NAS account username and password and click OK.
- The Device Details window appears.
Your device's Cloud Key is displayed in the Device Details window.
Method C: Use myQNAPcloud
- Log in to myQNAPcloudwith your QNAP ID:
- Login to myQNAPcloud.
- Go to Device Management.
- Locate and click on your device.
- Click Device Detail.
Your device's Cloud Key is displayed in the Device Detail tab.

If you cannot find your device's Cloud Key from the above methods, please contact QNAP customer support.
If you manually enable the "admin" account in Control Panel, you will need to specify a new password that is different from the Cloud Key of your device. If your firmware was updated from version 5.1.x or earlier, and you were using the default "admin" account with the default password, you will be required to change the password to something different than the Cloud Key of your device.
QTS/QuTS hero 4.4.2 - 5.1.x
The following default system administrator account is used:
Warning
To protect your system from malicious attacks, it is recommended to create a new administrator account and disable the default administrator account "admin".
- Username: admin
- Password: The first MAC address of the NAS in uppercase letters and without special characters. For example, if the MAC address was 00-08-9B-F6-15-75, the password is 00089BF61575
The MAC address sticker is physically attached to the rear of the NAS. If your NAS has multiple NICs, use the MAC address listed as MAC1:
In Qfinder Pro, the value is listed in the MAC Address column:
QTS/QuTS hero 4.4.1 - 4.3.6 or earlier
The following default system administrator account is used:
Warning
To protect your system from malicious attacks, it is recommended to create a new administrator account and disable the default administrator account "admin".

簡介
所有 NAS 設備都有預設系統系統管理員帳號「admin」。此帳號可以配置設定、建立使用者和安裝應用程式。此帳號無法刪除,並且根據您的 QTS/QuTS hero 版本,可能預設為停用。
「admin」帳號的預設密碼會根據您的 QTS/QuTS hero 版本而有所不同。請在繼續之前檢查您的版本。
如果在嘗試本文中的方法後仍無法登入 NAS,請在QNAP 社群論壇上發表您的問題並提供相關資訊以獲得進一步協助。
概念
了解 NAS 帳號 & Cloud Key & QNAP 帳戶
提示
- 我們建議在進行步驟之前,先了解這三個概念之間的差異。
- 每當您登入 NAS 或 QNAP 服務時,請仔細檢查系統要求您提供的帳戶型別。
NAS 帳號: NAS 帳號是您 QNAP NAS 上的本地帳號,用於登入此特定設備。"admin"是每台 NAS 預設建立的 NAS 帳號。對於 QTS/QuTS hero 5.2.0 及更新版本,此帳號預設為停用,並在系統重置後自動重新啟用。本常見問題解釋如何找回此預設"admin" NAS 帳號的密碼。如果您在設備設定期間創建了不同的系統管理員帳號,則本常見問題中描述的密碼不適用於該帳號。
Cloud Key:每台 QNAP NAS 都附有一個獨特的 Cloud Key,無論您是否配置了任何雲端設定。您通常可以在設備上的貼紙、快速安裝指南或 Qfinder Pro 的設備詳情中找到Cloud Key。對於 QTS/QuTS hero 5.2.0 及更新版本,此 Cloud Key 作為"admin" NAS 帳號的預設密碼。除此特定用途外,請勿將您的 Cloud Key 當作登入憑證。
QNAP 帳戶 (QNAP ID): QNAP 帳戶 (QNAP ID) 是用於存取各種 QNAP 服務(如 myQNAPcloud)並遠端管理您的 NAS 的帳號(通常是您的電子郵件地址或電話號碼)。您的 QNAP 帳戶和 NAS 帳號是不同的憑證,擁有不同的密碼。
詳細資訊
QTS/QuTS hero 5.2.0 及更新版本(如 5.2.x、5.3.x、6.0.0)
註
- 預設的 "admin" 帳號預設為停用,但在系統重置或系統還原後會自動啟用。為了保護您的系統免受惡意攻擊,我們建議創建一個新的系統管理員帳號並停用預設的系統管理員帳號 "admin"。
- 為了符合歐盟的網路安全要求,製造商必須避免使用通用的預設憑證。相應的歐盟 / 行業標準要求不使用通用預設密碼,必須為每個設備提供唯一的憑證或在首次使用時強制更改密碼。因此,從 QTS/QuTS hero 5.2.0 開始,預設的系統管理員密碼已更改為設備的Cloud Key(早期版本使用第一個網卡的 MAC;更早的版本使用 admin/admin),以符合這些要求。
預設系統管理員 NAS 帳戶的憑證:
- 使用者名稱:admin
- 密碼:您的設備的 Cloud Key,以大寫字母表示且不含任何特殊字元。例如,如果 Cloud Key 是Q1234-5678,則密碼是Q12345678
尋找您設備的 Cloud Key
您可以使用以下任何方法找到設備的 Cloud Key:
方法 A:從裝置貼紙或快速安裝指南中獲取
您可以從附在 NAS 機身上的貼紙或隨附的快速安裝指南中找到您的 Cloud Key。

方法 B:使用 Qfinder Pro
- 在沒有 NAS 使用者帳戶的情況下使用 Qfinder Pro:
- 關閉 NAS 電源。
- 從 NAS 中移除所有硬碟。
- 移除所有內部 M.2 SSD 和 QM2 PCIe 擴充卡(如果有的話)。
- 開啟 NAS 電源。
- 下載並安裝Qfinder Pro。
- 開啟Qfinder Pro。
- 選擇您的裝置。
- 按一下詳細資訊。
- 裝置詳細資訊 視窗隨即顯示。
您的裝置 Cloud Key 顯示在裝置詳細資訊視窗中。

- 使用 Qfinder Pro 與 NAS 使用者帳號:
- 下載並安裝Qfinder Pro。
- 開啟Qfinder Pro。
- 選擇您的裝置。
- 按一下詳細資訊。
登入視窗隨即顯示。輸入您的 NAS 帳號使用者名稱和密碼,然後按一下確定。
- [裝置詳細資訊 ]視窗隨即顯示。
您的裝置 Cloud Key 顯示在[裝置詳細資訊]視窗中。
方法 C:使用 myQNAPcloud
如果您無法透過上述方法找到裝置的 Cloud Key,請聯絡QNAP 客戶支援。
如果您在控制台中手動啟用「admin」帳戶,您需要指定一個與裝置 Cloud Key 不同的新密碼。如果您的韌體是從版本 5.1.x 或更早版本更新的,並且您使用的是預設的「admin」帳戶和預設密碼,則需要將密碼更改為與裝置 Cloud Key 不同的密碼。
QTS/QuTS hero 4.4.2 - 5.1.x
使用以下預設系統系統管理員帳戶:
警告
為了保護您的系統免受惡意攻擊,建議您建立一個新的系統管理員帳戶並停用預設的系統管理員帳戶 "admin"。
- 使用者名稱:admin
- 密碼:NAS 的第一個 MAC 位址,使用大寫字母且不含特殊字元。例如,如果 MAC 位址是00-08-9B-F6-15-75,則密碼為00089BF61575
MAC 位址貼紙實際上貼在 NAS 的後面。如果您的 NAS 有多個網卡,請使用列為MAC1的 MAC 位址:
在 Qfinder Pro 中,該值列在MAC 位址欄位中:
QTS/QuTS hero 4.4.1 - 4.3.6 或更早版本
使用以下預設系統系統管理員帳戶:
警告
為了保護您的系統免受惡意攻擊,建議您建立一個新的系統管理員帳戶並停用預設的系統管理員帳戶 "admin"。
