How to change the password of a workbook in Excel for Microsoft 365

New Contributor



I want to use a stronger password for an (entire) Excel file (i.e., a workbook) than the one I installed a year ago. 

I am aware of these articles:

Protection and security in Excel - Microsoft Support

Protect an Excel file - Microsoft Support


I need to remove the first password for the workbook, and then enter the new password. For some reason, it doesn't work as outlined in the article.


Any idea how I can do this?


Thank you!

Before you deal with password protection, you have to know in which levels and what type of password protection you already use.
