You can encrypt your Microsoft office document like Word, PowerPoint and Excel using a password thereby allowing no one can view the documents unless they have password. Today in this tutorial, I am going to provide you step by step procedure to encrypt your MS documents. We can apply following instructions for all Microsoft office software: Microsoft word, Excel and PowerPoint.
Protect word document with Password:
In Microsoft office 2003 and earlier versions, encryption options was very weak and we can easily bypass password protection using password cracking software. Microsoft researched deeply on protection and introduced AES (Advanced Encryption Standard) with 128-bit key in Microsoft office 2007 but even that wasn’t up to the standard.
So, Microsoft introduced two big things in Microsoft 2010. First, a new encryption technique for encrypting the documents (we can’t open the file without password or we can’t crack the password using any password cracking software). Second thing is setting a password to “Restrict Editing”. Anyone can view the document, but cannot edit without password. Let’s find out how you can protect your Word document with password in MS Office 2010.
Note: Always save and encrypt the word document in .docx format with password. Don’t save document in older formats like .doc because that’s not secure.
Step 1: Open word document and click “file” in the Top left corner of the screen. Click Info-> protect document-> Encrypt with password.
Note: In Restricted editing, secured documents can be easily cracked and removed.
Step 2: You have to choose password which is easy to remember and difficult to guess for protecting your document. When you are encrypting the document, you can see a dialogue box with “Encrypt the content of this file: password”. Then enter your password and click “Ok”.
Warning: If you forgot the password, you can’t access the document forever. Microsoft recommends you to note down the password with document name and keep it safe for reference.
When you open the encrypted word document, you have to enter correct password and if you don’t enter it you can’t view the document.
To remove password protection, click “file” in the Top left corner of the screen. Click Info-> protect document-> Encrypt with password and enter blank password and click “OK”.
Now you know how to protect word document with password. You can follow the same procedure if you would like to protect workbook and Microsoft office presentation software’s with passwords.
