Solution 1Recommended

Enable and Use OneDrive Personal Vault

Since OneDrive does not offer individual file passwords, setting up Personal Vault provides a highly secure, secondary authentication layer for your most sensitive files.

OneDrive encrypts all data while it is transmitted and stored, even for the free 5 GB plan. However, for specific files that require strict access control, Personal Vault acts as a locked folder within your cloud storage.

1
Locate the Personal Vault

Open your OneDrive account in a web browser or the desktop app, and click on the 'Personal Vault' folder icon.

2
Verify your identity

Follow the on-screen prompts to set up and verify your identity using a PIN, fingerprint, facial recognition, or an approval from the Microsoft Authenticator app.

3
Move files into the Vault

Once unlocked, drag and drop your sensitive documents into the Personal Vault. The vault will automatically lock after a period of inactivity, keeping your files secure.

Enable and Use OneDrive Personal Vault
Personal Vault Limits: Depending on your specific account status, the free version of OneDrive may have limits on the number of files you can store inside the Personal Vault without a Microsoft 365 subscription.

Password Protect Individual Files Easily with WPS Office

While OneDrive doesn't allow you to password-protect individual files directly, WPS Office solves this by letting you encrypt any document, spreadsheet, or presentation with a custom password before uploading it to your cloud storage.

  1. 1. Open your file in WPS Office: Launch WPS Office and open the document, spreadsheet, or presentation you want to protect.
  2. 2. Access the encryption menu: Click on the 'Menu' tab in the top left corner, navigate to 'Document Encryption', and select 'Encryption'.
  3. 3. Set a secure password: Enter a strong password in the 'Document Password' field and re-enter it to confirm. You can also set separate passwords for modifying the document.
  4. 4. Save the encrypted file: Click 'OK' and save your file. You can now safely upload this password-protected file to OneDrive or any other cloud service.

Frequently Asked Questions

Is data on the free OneDrive plan encrypted at rest?

Yes, Microsoft encrypts all OneDrive data both while it is in transit (being uploaded or downloaded) and at rest (stored on their servers), even if you are on the free 5 GB plan.

Can I put a password on a specific folder in OneDrive?

OneDrive does not support adding traditional passwords to standard folders. To protect a specific folder, you must use the Personal Vault feature, which requires additional authentication to open.

What happens if I forget my Personal Vault PIN?

If you forget your PIN, you can reset it by verifying your identity using another security method linked to your Microsoft account, such as an alternative email address or an SMS code.

Does password protecting a file in WPS Office work when uploaded to OneDrive?

Yes. If you encrypt a file with a password using WPS Office and upload it to OneDrive, the file remains encrypted. Anyone who tries to download and open it will still be prompted to enter the password you set.
