Do you have a confidential Excel, Word or PowerPoint file? Here's how to protect it with a password. Microsoft Office allows you to secure any document with a code. The file is then automatically encrypted and can only be read when the password is provided.
Almost everyone has a password on their Windows or macOS account or even a lock code on their smartphone. Some Word, Excel or PowerPoint files deserve the same precaution because you are never safe from indiscretions or because by dragging them around on a USB key or an external hard drive, they risk falling into the hands of 'a stranger. This constitutes a double penalty if these documents contain confidential or sensitive data.
