Help making a macro to unprotect 2+ workbooks that have the same password

Hi there,

First time poster here, I am wondering if there is a way to mass-unprotect multiple workbooks at once. I basically have one directory, and all of the individual .xlsm files are in there. There are around 400 individual workbooks, some of which are protected, while others are not. Of the ones that are protected, all of them have the same password. Can someone help me figure out a way to unprotect all of them at once? I am still really new to VBA, so a breakdown of what's going on in the code comments would be really nice too.

Thank you!

I do have the password for all of these files.

I do have the password for these files, yes.
