Quick Protect allows you to protect all the worksheets in a workbook in a single pass.
- Password: Optional password to secure the sheet protection. (Note: Spreadspeed does not save the password. It uses the built-in password protection mechanism provided by Excel.)
- Hide password characters: Determines whether the password characters are displayed as you type them.
- Apply to: All worksheets plus workbook structure  or just the active worksheet.
- Unlock cells with these styles: After protection, check cell types can be edited, and all other cells are locked. These feature leverages built-in and custom styles to determine whether cells are unlocked.
 Workbook structure affects the order of the sheet tabs, sheet names, and whether sheets can be added, deleted, or hidden and unhidden.
