You can restrict which users can open or modify a document by using password protection. When you use password protection, users must enter a password before they can open or change the password-protected document. Standard passwords in Word are case sensitive, they can be up to 15 characters long, and they can contain any combination of letters, numerals, spaces, and symbols.

Tip - Create passwords longer than 15 characters

If you want to create passwords that are longer than 15 characters, you can do so (up to 255 characters) by choosing another encryption type for your document. To do this, choose Tools, Options, click the Security tab in the Options dialog box, click the Advanced button, and choose an RC4 encryption type in the Encryption Type dialog box.

To protect a document by assigning a password, open the document, choose Tools, Options, and click the Security tab in the Options dialog box, shown in Figure 34-1. Many of Word's security features are accessible from the Security tab.

Figure 34-1. The Security tab in the Options dialog box provides a number of security-related settings.

After you display the Security tab, you can create a password that restricts who can open or modify the current document by performing one of the following actions:

• Assign a password to open. On the Security tab, enter a password in the Password To Open box, and click OK. The Confirm Password dialog box appears. In the Reenter Password To Open box, type your password again, and click OK. Save the document to complete the process.
• Assign a password to modify. On the Security tab, enter a password in the Password To Modify box, and click OK. The Confirm Password dialog box appears. In the Reenter Password To Open box, type your password again, and click OK. Save the document to complete the process.

After you assign a password to open a document, the Password dialog box will appear whenever someone attempts to open the document, as shown in Figure 34-2. To open the document, the user will have to enter the correct password and click OK. If a user doesn't know the password, he or she can click Cancel to abort the process.

Figure 34-2. Before users can open a password-protected document, they must enter the correct password in the Password dialog box.

Similarly, after you assign a password to grant users modification privileges, they'll see a Password dialog box like the one shown in Figure 34-3 when they open the document.

Figure 34-3. When a document is password protected for modification, users can open the document in read-only format, even if they don't know the password required to make changes.

In this Password dialog box, users can perform any of the following actions:

• Enter a password in the Password box and click OK, which enables users to open and modify the document.
• Click Read Only, which enables users to view the document without enabling them to modify the original version of the document.
• Click Cancel, which aborts the entire process.

If users open the document by clicking the Read Only button, they'll be able to make changes to the document, but they'll be able to save the modified document only as a new file—they won't be able to replace the existing version of the file with their modified version.

Tip

To remove password protection, you must know the passwords to gain access to the document. After you open a password-protected document, you can delete the passwords (which appear as asterisks) on the Security tab; deleting password information on the Security tab removes the password protection. To do this, choose Tools, Options, click the Security tab, and delete the passwords in the Password To Open and Password To Modify boxes. Then click OK and save the document to complete the procedure.
