How to set protection and encryption in PowerPoint?

php Editor Yuzi: Want to protect your PowerPoint presentation from being viewed or edited by others? Then setting up password protection and encryption is an essential step. With simple operations, you can easily add a password to your PowerPoint document to ensure the security of the document. Next, we will introduce in detail how to set up protection and encryption in PowerPoint to make your files more secure and reliable.

Open PPT, click the menu [File], and then click [Information]-[Protect Presentation], you can see 5 options for setting password protection.

.

Option 1: Always open read-only

There is no need to set a password when selecting this option. Once clicked, the setting will be completed. When the PPT is opened again, it will be in "read-only mode".

The PPT in this mode cannot be edited or modified, but you can edit it by clicking [Edit Anyway] in the menu bar.

.

Option 2: Encrypt with password

This item is used to set the "open password", that is, you need to enter the correct password to open the PPT document.

After clicking the option, a dialog box will pop up. Enter the password you want to set in the blank column. Click [OK] and enter it again to complete the password setting.

.

When you open PPT again, you will be prompted to enter a password to open the file.

.

Option 3: Restrict access

Through this item, you can set multiple users (email accounts). Different users can also set different permissions, but they need to be logged in to Office and connected to the Internet to use it.

.

Option 4: Add digital signature

Adding a digital signature can protect your property rights and ensure that there is no risk of changes to the PPT.

But options 3 and 4 both require connecting to the server to obtain relevant permissions or signing certificates, which is relatively cumbersome.

.

Option 5: Mark as final

Selecting this option indicates that the editing of the PPT has been completed and is the final version of the document, which cannot be modified.

This is also a password-less protection method. After clicking to pop up a new interface, select [OK] to complete the setting.

.

After setting, PPT cannot be edited or changed, but like option 1, click [Edit Anyway] above the document to lift the restriction.
