How to password protect a word document

If you have a word document containing important/sensitive information, it is a good idea to password protect the document. This means the document will not be accessible to anyone who doesn't know the password. There's also an option which allows a person to open and view the document, but not save any changes to it.

1. Open the word document
2. Go to the tools menu, and choose 'Options'
   
3. Click on the security tab
   
4. Type the password in. You have a choice of password protecting the document (and preventing anyone from viewing it), preventing them modifying it or both.
   
5. Next time anyone tries to open/modify the document, they will have to enter the password.
