Often there is a need to protect a written document from editing or even just from opening by an unwanted user. This may be personal data that no one else should see but you. The easiest way to protect your document is to set a password that will be asked when you try to open it.

Instructions
Step 1
First of all, configure the settings of the program in which your document will open. To do this, open the document that needs protection. Find the "Service" item in the top menu bar, the "Options" sub-item in the drop-down menu.
Step 2
Go to the "Security" tab. All parameters related to the safety of your document are grouped here. In this column, you can set a password for opening a file, a password for permission to write, set read-only access, protect a document from macros, and so on. Choose all the settings for yourself based on the importance of the document.
Step 3
Set a password to open a document. You shouldn't choose a password consisting of a simple word. Password cracking programs will pick up such a password in a matter of minutes. Come up with a combination of numbers and letters that you can easily remember. For example, your friend's name and date of birth. However, it is worth noting that such passwords, if desired, can also be obtained using social engineering. Try to set a strong password, and at the same time, not difficult for you.
Step 4
Save your changes and close the document. Now, when you try to open this document, a dialog box will appear asking for a password to open this file. If the password is incorrect, a message will appear stating that the password you entered is incorrect and the document will not be opened. Try to protect your computer as much as possible so that there are no problems in the future with viruses or Trojans that steal files, passwords, all data from the computer. All protection of a personal computer largely depends on you, and on the configuration of certain software.
Step 5
Microsoft software developers have foreseen various issues related to writing and using documents. It is easy to protect a document: just set a password to open it, or to make changes.
