Do you have a confidential Excel, Word or PowerPoint file? Here’s how to protect office document with 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 supplied.
Almost everyone has a password on their Windows account , macOS or a lock code on their smartphone. Some Word, Excel or PowerPoint files deserve the same precaution because you are never safe from indiscretions or by dint of carrying 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.
Excel, Word, PowerPoint: how to protect office document with a password
The passwords in a Word, Excel or PowerPoint are case sensitive and are limited to a maximum of 15 characters. Please make a note of the code in a safe place, because if you forget it, Microsoft Office does not offer a time to recover it.
The document therefore becomes permanently inaccessible. Here we use a Word document for illustration, but the process is the same for Excel and PowerPoint.

- Fill in the password of your choice then confirm. For more security, do not hesitate to consult our advice for choosing a strong password.
