When you have a Word document that has a lot of content you don't want someone to see, you have several options to password protect the document. These protections are available for all versions of Word in varied degrees although you may not be able to use them on Word Online. These protections can be very helpful in allowing you to protect sensitive content.

But which protections do you use? When selecting the type of protections to apply to any Word document, the reasons for protection can be a determining factor. In this article, we are going to be looking at various ways you can use to lock a Word document and prevent anyone without a password from accessing the file.

1. Mark as Final

One of the easiest ways to protect Word document from further editing is to "Mark as Final". Marking a Word document as final will inform anyone that the document is complete and marked as "Read only" preventing anyone from making any changes to it. This will hide any editing marks, comments and tracked changes on the document and a pop up will appear on the document, informing the reader that it has been marked as final.

It is a less secure way to lock a Word document since the reader can simply click on "Edit Anyway" to change the document. It is however a very effective way to openly share content while letting the reader know that the document is complete.

2. Encrypt with Password

The other way to password protect word is to encrypt it with a password. When the document is encrypted in this way, anyone who opens it will need a password to access the content on the document.

You can use a password to encrypt a Word document by clicking on "File > Info > Protect Document" and then enter the password you want to use in the dialogue box that appears. Then enter the password again to confirm it.

This method is a lot more secure since anyone without a password will not be able to open the document. It is important to note however that this method doesn't include a recovery option and you may be unable to access the document if you lose the password.

3. Restrict Editing

You may also choose to lock a word document by restricting editing. Restrict Editing is an option that is available under the "Review" tab. After you choose to restrict editing on the Word document, you will have 2 options:

  • Formatting Restrictions - prevents the reader from making changes to the document. You can also click on "Settings" to select the allowed styles.

  • Editing Restrictions - You can restrict the type of editing that can be done on the document or even cancel editing permissions completely. You may also be able to specify users who can edit the document by clicking on the "Exceptions" or "More Users" option.

To make these changes take effect, you must click on the "Yes, Start Enforcing Protection" button in the "Restrict Editing" toolbar.

4. Protect Word Document on Mac

You may have already noticed that there is a slight difference of procedure when protecting a document in Word for Windows and Word for Mac. If you are using Word for Mac, follow these simple steps to protect a Word document from being opened or edited:

Step 1: Open the Word document you would like to protect and then click on "Review > Protect Document".

Step 2: Under "Security", you will need to choose if you want to set a password to open the document. Set a password to modify the document or both. Type in the password you want to use and re-type it to confirm.

Step 3: Click on "OK".

Keep in mind that passwords you use are case sensitive and cannot be longer than 15 characters long. There is also no way to recover the password, so be sure to set a password that is easy to remember and keep a copy of it somewhere safe so you can access it when you need it.

5. How Unlock Word Document If Password is Lost

While Word does offer you amazing ways to protect your Word document and restrict editing, it can be very hard to recover the password if you lose it, especially if you are using older versions of Word. This means that if you ever lose the password you used to encrypt the document, you may be unable to access the document and thereby lose all the content on it without the possibility of being able to recover the content.
