Do you have a confidential Excel, Word or PowerPoint file? Here's how to protect it with a password. Microsoft Office makes it possible to secure any document with a code. The file is automatically encrypted and can only be read when the password is provided.


Almost everyone has a password on their account Windows, macOS or a lock code on his smartphone. Some Word, Excel or PowerPoint files deserve the same precaution because one is never safe from indiscretions or by pushing them on a USB key or an external hard drive, they risk falling into the hands of 'a stranger. This is a double penalty if these documents contain confidential or sensitive data.
