Password-protect a Keynote presentation on Mac
You can assign a password to a presentation so that only those who know the password can open the presentation. Passwords can consist of almost any combination of numerals, capital or lowercase letters, and special keyboard characters.
A presentation can have only one password. If you change an existing password when you share a presentation with others, the new password replaces the original. If you add a password after you share a presentation, make sure you notify participants.
Important: There’s no way to recover your password if you forget it. Make sure you choose a password you won’t forget, or write the password down in a safe place.
If your computer has Touch ID, the fingerprint detection feature, you can use it to open your password-protected presentations with your fingerprint alone.
Require a password to open a presentation
Go to the Keynote app
on your Mac.Choose File > Set Password (from the File menu at the top of your screen), enter the requested information, then click Set Password.
If your computer is set up for Touch ID, “Open with Touch ID” appears. You can select the tick box to turn on Touch ID for the presentation.
If your computer isn’t set up for Touch ID, “Remember this password in my keychain” appears. You can select the tick box to add the password to your keychain so you don’t have to type the password each time.
Note: Adding a password to a presentation encrypts the file.
Change or remove a password
Go to the Keynote app
on your Mac, then open a password-protected presentation.Do one of the following:
Change a password: Choose File > Change Password (from the File menu at the top of your screen). Enter the requested information, then click Change Password.
A presentation can have only one password, so if you change the password when you share the presentation, that becomes the presentation’s only password.
Remove a password: Choose File > Change Password. Type the old password, then click Remove Password.
People you invite to collaborate on a presentation and who have editing permission can add, change or delete the password.
Set up Touch ID to open password-protected presentations
Before you can use Touch ID to open password-protected presentations, you need to set it up on your computer.
To set up Touch ID, do the following:
On your Mac, choose Apple menu
Click add Fingerprint, then follow the onscreen instructions.
Go to the Keynote app
, choose Keynote > Settings in the menu bar, then select the tickbox for Use Touch ID.
Open a password-protected presentation with Touch ID
Go to the Keynote app
on you Mac.Double-click the password-protected presentation, then place your finger on Touch ID.
If you add a password to a presentation, or change an existing password, the password applies only to the version where the password was added or changed and to subsequent versions.
If the presentation is shared, to prevent others from restoring an unprotected version of the presentation or a version with an older password, stop sharing the presentation, add a unique password to it, then share the presentation again.
Note: You can also protect a presentation by requiring a separate password to stop or exit the presentation while it’s playing. This password requirement is useful, for example, when the presentation is set to play automatically in a kiosk.
