If you share a computer or just want to add a little extra protection to an OpenOffice document, it’s pretty easy to protect it with a password.
Start by opening or creating a document.
Click the File tab at the top left and choose Save as from the drop-down menu.
When your save as options open, look at the bottom.
Tick the box next to Save with password.
Choose your password.
Click the arrow next to More Options.
You can require a file sharing password or set the document to open as read-only.
Click OK to save your changes.
