Recently, Microsoft is making a change to its Microsoft Office branding. Microsoft Office is being renamed by Microsoft 365. After the official renaming, our article content will be updated accordingly.

Are you responsible for keeping private and sensitive information in Microsoft Word documents? If so, it is best for you to password-protect these files. If there is a chance that someone will look through your confidential documents, this password security option is advantageous.

So, in this article, you will find three methods to safeguard your Word document from prying eyes. Read on to find out more. You can use the built-in feature, encryption, or draw signature in Word documents to password-protect the files. 

Method 1. Password Protect Word Document in Word

Microsoft Office Word offers a built-in security method for all Office products, including Word. This feature can encrypt the document with a password, ensuring nobody can use any backdoor software to get the data from the Word document.

If you only want to restrict edits or access, you can choose from the options shown below.

Method 2. Add a Digital Signature to Word Document

A digital signature is an electronic, encrypted authenticating sign placed on digital material like emails, macros, or electronic documents. A signature verifies that the document is authentic and was not altered. So, you can electronically sign a Word document to protect it.

Add A Digital Signature to Word

Here are the steps to add a digital signature to a Word document:

Step 1. Open the Word document into which you want to insert the digital signature. Go to "File > Info > Protect Document" and choose "Add a Digital Signature" from the drop-down menu.

Step 2. In the "Sign" window, choose and fill required details for "Commitment Type and Purpose" for signing this document.

Step 3. Next, click on the "Details" button, fill in the details in the "Additional Signing Information" window, and press "OK".

Step 4. Press the "Sign" button, and you will get a message that your sign has been successfully saved in the document.

Method 3. Make an Encryption in Windows Explorer

Microsoft Windows offers built-in encryption for all files and folders. You can use Windows Explorer to protect your data by encrypting it. The person with the correct encryption key or password can decrypt it.

In the background, this feature uses BitLocker to encrypt the file; hence, it will work on Windows Pro and above but not the Windows Home version. When setting this up, remember the BitLocker password or open it on a PC where you have set up "BitLocker" using the same Microsoft account.

Make An Encryption in Windows Explorer

Here is how to encrypt your Word document using Windows explorer:

Step 1. Go to "File Explorer" and find the Word document you want to encrypt. Right-click on the document and choose "Properties".

Step 2. Go to the "General" tab and choose the "Advanced" option.

Step 3. Check the box next to "Encrypt contents" to secure data and click "OK".

Step 4. Next, click "Apply" and then "OK". Your Word document is encrypted.
