Depends on what type of access, "YOU" need with 'so called' master password.

If access only to edit the cells is OK for you then it can work as under:
Click on Tools Menu - Allow User to Edit Ranges
In the box that will appear click on 'New'.

In Refers to Cells: Filed enter " =1:65536 " (Without quotation marks!)
(This refers to entire workseet range).
Enter YOUR 'Master' password in the Range Password and click on OK.

Repeat this for all sheets if you wish.

Now the user can protect the sheet with his password.

when you want to edit a cell, click on it, it will prompt for Edit Range
Password,
enter it and you can edit (change) the cell.

Is it possible to protect a sheet with a master password and still let
someone create their own password?

I would like to create individual workbooks for members were they can
create
their own password, yet I would still like to access them all with one
master
password. Is this possible?
