This quick guide will teach you how to protect a LibreOffice document with a password.
There are four types of protection available in LibreOffice. They are –
- Protecting a document with a password while saving (uses a password)
- Protecting revision making (uses a password)
- Protecting frame, graphics and OLE objects
- Protecting drawing objects, frame objects
Important Note: If you forget/lose the password which was used to protect the document, you will never be able to open the document. Because LibreOffice encrypts the document with strong encryption. So, it is recommended to save the password using any password manager or memorize it.
