Adobe Acrobat Pro DC – securing documents with password.
You can protect a PDF document from unauthorised access by setting a password to the document.
Important: If you forget the password, there is no way to reset and you will never be able to access the file. Consider keeping a backup copy of the original PDF document in a safe location.
Microsoft provides a password-protection feature for you to safeguard your Office documents such as Word, Excel and PowerPoint files.
A password is case-sensitive and can consist of up to 255 characters. We highly recommend you to set a password with at least 8 characters. Microsoft adopts AES 128-bit advanced encryption by default. You can choose other encryption techniques if you want. When choosing a password, you may consider to combine upper and lowercase letters, numbers and symbols for a stronger protection. For instance, Y68h!et5 is a strong password whereas House27 is a weak one. It is important that you must remember your password. If you forget your password, ITO or even Microsoft is not able to open your Office documents.
The procedure for setting password in Microsoft Office documents is as follows
