Password Protect Files For Mac


Word Online can’t encrypt a document with a password, and it can’t open documents encrypted with a password. If you want to protect the file with a password, click or tap Open in Word to open your document in the desktop version of Word. After you've added password protection, you’ll need to use the Word desktop program to open the document.

Work from home has enabled a new workflow for the majority of folks. No working directly with co-workers and take coffee breaks in the office. Also, sharing sensitive documents and passing files among employees online has become a bit stressful. After all, you won’t want any third-party to get access to the latest quarterly earnings, sales report, or your hard-earned client lists. For security, add a layer of authentication on PDF files you share in Slack, Zoom, or Skype.

One can upload the PDF file to OneDrive and add an expiry time to a shared weblink. Or even better, you can add a password and limit the PDF access to a specific group of people.

  • Caution: When you create a password for a document, write down the password and keep it in a secure place.If you lose the password, you can't open or gain access to the password-protected document.Passwords in Excel for Mac and Word for Mac have a 15-character limit.
  • In the Preview app on your Mac, open the PDF you want to password-protect. Choose File Export, then select Encrypt. Type a password, then retype it to verify the password.

Windows and macOS offer native options to password protect PDF. If you are not happy with the built-in solution, then you can always opt for a third-party app from the web. Let’s get started with Mac.

Second, you can purchase the subscription and use the service on other platforms such as Mac, Linux, and Chrome OS because it's web-based. Now, go through the steps below.

Step 1: Open to Small PDF site in the web browser.
