At times when we need to save some confidential data or details that we dont wish others to access or make changes to, we need to encrypt or password protect our files. Here we will show how to password protect your files in MS Word 2007. Once your word document is ready and you have saved the file to some location, click the "Home" button and from the dialog box there, select the "Prepare" button and then "Encrypt Document" On clicking the "Encrypt Document" a popup window will open to encrypt the contents of the file, where you need to enter a password to protect your document. Once entered click on "OK". One thing that needs to kept in mind which will also be mentioned in the "Encrypt Document" window is that it is advisable to keep a password that you will remember or keep it written in a safe place that it can be retrieved from because if you forget the password the document cannot be recovered. On completion of the above step, another window would open to confirm the password. Retype the password and click on "OK" Now your document is password protected and so the next time that you open it you will encounter this password box where you need to enter the password before the contents of the document can be viewed. If you have entered the correct password, your document opens up. This way all your data can be kept secure and no one can mess with it.
