OneNote - Password Protect your Notes

Password protection in OneNote is designed to help keep your notes safe from prying eyes. Whether you use OneNote for class notes at school, meeting notes at work, a personal diary or blog at home, or personal information about yourself or your friends and family, passwords play a crucial part in controlling access to those notes.

To Set your Password:

1. Right-click the section tab you want to protect and then choose Password Protect this Section.

2. In the Password Protection task pane, choose Set Password.

3. In the Password Protection dialog box, type the password you want into the Enter Password box.

4. Confirm the password by typing it again into the Confirm Password box, and then click OK.

*Note: Choose your password carefully. If you forget your password, no one will be able to unlock your notes for you (not even Microsoft Technical Support).

To Lock your Sections:

1. Right-click any of the protected (but currently unlocked) section tabs and then choose Password Protect this Section.

2. In the Password Protection task pane, choose Lock All.

3. Now you will need to insert passwords to access to your notebook sections.

To Remove Passwords:

1. Right-click the section tab that has the password you want to remove, and choose Password Protect this Section.

2. In the Password Protection task pane, choose Remove Password. (If this option isn’t available, it means the section doesn’t have a password.)

3. In the Remove Password dialog box, type the current password, and then click OK.

Some important notes about passwords:

1. Passwords can be applied only to notebook sections, not to entire notebooks.

2. Passwords are case-sensitive. Make sure that the Caps Lock key is off before you create or enter a password.

3. Password-protected sections aren’t included in notebook searches. To include a protected section in a search, you’ll have to unlock the section first.

4. Note tags used on any of the pages within a protected section aren’t included in a note tag summary unless the protected section is unlocked.

您能使用密碼保護 OneNote 筆記本的節,以確保您的私人筆記不受窺探。當某個節受到密碼保護時,其所有頁面都會鎖定直到您輸入正確的密碼。


1. 以滑鼠右鍵按一下您要保護的節索引標籤,然後選擇 [以密碼保護此節]。

2. 在 [密碼保護] 工作窗格中,選擇 [設定密碼]。

3. 在 [密碼保護] 對話方塊的 [輸入密碼] 方塊中輸入所要的密碼。

4. 在 [確認密碼] 方塊中再次輸入密碼以進行確認該,然後按一下 [確定]。

*附註: 請謹慎地選擇您的密碼。如果您忘記密碼,誰都無法解除鎖定您的筆記 (甚至 Microsoft 技術支援也沒辦法)。


1. 如果您已經為筆記本中的多個節套用密碼,則可以同時鎖定所有節。

2. 請以滑鼠右鍵按一下任何受保護 (但目前已解除鎖定) 的節,然後選擇 [以密碼保護此節]。

3. 在 [密碼保護] 工作窗格中,選擇 [全部鎖定]。


1. 以滑鼠右鍵按一下要移除密碼的節索引標籤,然後選擇 [以密碼保護此節]。

2. 在 [密碼保護] 工作窗格中,選擇 [移除密碼]。(如果此選項無法使用,表示該節並沒有密碼。)

3. 在 [移除密碼] 對話方塊中,輸入目前的密碼,然後按一下 [確定]。


1. 密碼只能套用至筆記本的節,不能套用至整個筆記本。

2. 密碼區分大小寫。建立或輸入密碼之前,請確定已關閉 CAPS LOCK 鍵。

3. 受密碼保護的節不會包含在筆記本搜尋中。若要將受保護的節包含在搜尋中,您必須先解除鎖定該節。

4. 除非解除鎖定受保護的節,否則受保護的節內任何頁面上所用的筆記標籤都不會包含在筆記標籤摘要中。
