Password protect a document

Help protect a sensitive or confidential document from unwanted edits by assigning a password. You can also prevent a document from being opened.

1. Click File > Info > Protect Document > Encrypt with Password.

1. In the Encrypt Document box, type a password, and then click OK.

2. In the Confirm Password box, type the password again, and then click OK.

Notes: 

• You can always change or remove your password.

• Passwords are case-sensitive. Make sure that the CAPS LOCK key is turned off when you enter a password for the first time.

• If you lose or forget a password, Word can't recover your information, so keep a copy of your password in a safe place or create a strong password that you'll remember.
