How to protect an Excel, Word or PowerPoint file with a password

Do you have a confidential Excel workbook, Word, or PowerPoint file? Here’s how to protect your file with a password. Microsoft Office allows you to secure any document with a password. The data is then automatically encrypted and can only be read when the password is provided.

Almost everyone has a password on their Windows account, macOS or a lock on their smartphone. Some Word, Excel, or PowerPoint files require the same caution because by keeping them around on a USB stick or external hard drive, they may fall into the stranger’s hands. This can lead to big troubles if these documents contain confidential or sensitive data.

Excel, Word, PowerPoint: how to protect an Office document with a password

Passwords on Excel sheets, Word, or PowerPoint files are case-sensitive and are limited to a maximum of 15 characters. Please note the code in a safe place because if you forget it, Microsoft Office doesn’t have an option for recovery. The document thus becomes permanently inaccessible. We use a Word document here for illustration, but the process is the same for Excel and PowerPoint.

Open the Office file you want to protect by password

Protect document. In the drop-down menu of Word, Excel, and PowerPoint

Go to file> Protect document. In the drop-down menu that opens, select Encrypt with a password

Enter the password of your choice and confirm. For more security, don’t hesitate to check out our tips for choosing a strong password.

How do I remove a password from an Excel workbook, Powerpoint, or Word document

First, if you want to delete the password from an Office file that doesn’t belong to you, this is impossible. To do so, you must enter the code that protects it beforehand.

Open the Office document.

Enter the password.

Go to File – Protect document. Choose the Encrypt with a password option.

Clear the password and leave the field empty.

Click Ok.

That’s as simple as that. You can now put a password and delete it from an Office document. Microsoft offers other options to protect Word, Excel, and PowerPoint files. In particular, it is possible to force their opening in “reading alone” mode or to restrict the change (control the types of changes that other people can make). These options are also available in the File Info Drop-down menu Protecting Document.
