The first step in how to password protect a Word document is simply opening the file you want to protect.
- On your computer, launch Microsoft Word.
- Open the document you want to lock.

Step 2: Access the “Protect Document” Option
Once your file is open, go to security settings to learn how to password protect a Word document.

- Choose Encrypt with Password.
For Mac Users:

Step 3: Set a Strong Password
A pop-up window will appear asking you to type a password. This is where you create the lock for your document.
Tips for a strong password:
- Use at least 12 characters.
- Combine uppercase letters, lowercase letters, numbers, and symbols. Example: Sunset@Glow #42!
- Avoid common passwords like “password123” or your name.
Once you type your password, click OK.
Important: If you forget your password, Microsoft cannot recover it. Always store it in a safe place.
Step 4: Confirm Your Password

Your document will only be secure after you save it.

Sometimes you may want people to view your file but not make changes. You can do this without blocking access completely.
For Windows:
- Go to File, then Info, Protect Document, and Restrict Editing.
- Check: Allow only this type of editing.
- Select No changes (Read only) from the dropdown.
- Click “Yes, Start Protection” and set a password.

What If You Forget Your Password?
If you forget the password, recovering the file is hard. Here’s what you can try:

- Try older passwords you have used before.
- Consider professional recovery tools like PassFab for Word (paid option—use with caution).

With password encryption, even if someone gets access to your file, they won’t be able to read or edit it without your permission.
