Protected cells cannot be changed, moved or copied without first being unprotected.

Protection can be secured using passwords.

However this has no effect until the worksheet itself is protected.

Properly designed worksheets usually have a combination of protected and unprotected areas.

To create a worksheet with a mix of protected and unprotected cells you must unlock the cells you wish to be able to change before protecting the worksheet.
