Encrypt Individual Word Documents with a Password

The most reliable way to secure a specific file regardless of where it is stored is to apply a document-level password.

Applying a password directly to a Word document ensures that even if someone gains access to your PC or OneDrive account, they cannot open the file without the specific password.

Open the sensitive document

Launch Microsoft Word and open the document you wish to protect.

Access the Info menu

Click on the 'File' tab in the top-left corner of the window, then select 'Info' from the left sidebar.

Encrypt the file

Click on 'Protect Document' and select 'Encrypt with Password' from the drop-down menu.

Set and confirm your password

Type a strong password in the prompt, click 'OK', re-enter the password to confirm, and then save the document.

Frequently Asked Questions

Can Microsoft recover my Word document password if I forget it?

No, Microsoft cannot retrieve or reset a forgotten document password. It is highly recommended to use a trusted password manager to store your document passwords securely, as losing the password means losing access to your data forever.

Are OneDrive files encrypted on the server?

Yes, OneDrive encrypts your data both in transit and at rest on their servers. However, if someone gains access to your Microsoft account credentials, they can view your files natively, which is why enabling multifactor authentication (MFA) is crucial.

Does full-disk encryption protect my files when my computer is turned on?

Full-disk encryption, like BitLocker, primarily protects your data if the physical device is lost, stolen, or powered off. When the computer is powered on and you are actively logged into your account, the files are decrypted and accessible, highlighting the need for individual document passwords for highly sensitive data.
