Hence, we’ll take you through ways to password-protect Word documents on your PC. Also, we have a detailed guide about Word documents being blank when opened and some steps for fixing the issue.

Why do I need to password-protect a Word document? Password Protect is a feature in Microsoft Word that allows users to create a document and set a unique password to protect it. The sole purpose of the security system is to prevent unauthorized users who happen to have the document from editing or making adjustments.

Furthermore, adding password protection to your Microsoft Word document keeps the contents safe from prying eyes. It limits access to the document by allowing a group of selected individuals with a password to access and edit it.

How can I password-protect a Word document?

1. Use the Encrypt with Password option

  1. Launch the Microsoft Word app on your computer.
  2. In the top-left corner, click the File tab, then select Info from the left sidebar.
  3. Click the Protect Document button on the right pane, then select the Encrypt with Password option.
  4. On the new prompt, type a password to protect the document, then click the OK button.
  5. Retype the password and click the OK button.
  6. On the left sidebar, click the Save button to keep the changes.

Encrypting with a password means every time you open the document, you’ll be prompted to enter a password to decrypt its contents. It prevents unwanted access to the encrypted document. Also, it makes it virtually impossible to open the document.
