To password protect a presentation in Keynote on Mac, open the file and choose File > Set Password, then type the password and click Set Password. Keynote encrypts the file, so anyone who opens it has to enter that password first.

## Quick answer

- Open the presentation, then choose File > Set Password, enter the password and click Set Password.
- Keynote encrypts the file. Anyone who opens it must type the password first.
- Tick Open with Touch ID if you see it. Otherwise tick Remember this password in my keychain.
- Apple says it cannot recover a forgotten password, so store it somewhere you can reach.
- The slideshow exit password is a different setting, under Keynote > Settings > Slideshow.

Applies to: Keynote 15.x for Mac, with macOS 26 or later. Time: 5 min. Difficulty: Easy.

## What you need

- A Mac with Keynote 15.x installed, running macOS 26 or later for Keynote 15.4
- The presentation saved on your Mac or in iCloud Drive
- A password you can remember, or a password manager to store it
- Touch ID set up on the Mac, if you want the fingerprint option

## How to Password protect a Keynote presentation in Keynote on a Mac

1. **Open the presentation.** (File > Open) Shortcut: ⌘O. Launch Keynote, then open the presentation you want to protect. Use File > Open, or double-click the file in Finder. Tip: Protect the final version. Set the password on a copy you no longer change.
2. **Choose Set Password.** (File > Set Password) Click File in the menu bar, then choose Set Password. Keynote opens a dialog that asks for the information it needs to lock the file.
3. **Type and confirm the password.** Type the password in the first field. Type it again to confirm. Fill in any other field the dialog shows. Choose a password you can remember, or store it safely. Tip: Use a long phrase with spaces, and keep a copy in a password manager.
4. **Choose the keychain or Touch ID option.** If Touch ID is set up on this Mac, tick Open with Touch ID. If it is not, tick Remember this password in my keychain. Leave both unticked if you want to type the password every time. Tip: The keychain box matters later. It is the only documented way to get a lost password back.
5. **Click Set Password.** (Set Password) Click Set Password to encrypt the file. The dialog closes, and the presentation stays protected from that point on.
6. **Save the file.** (File > Save) Shortcut: ⌘S. Save the presentation so the protected version is written to disk. Press ⌘S, the standard macOS save shortcut. Apple's password pages do not list a shortcut for the password steps. Tip: If the file lives in iCloud Drive, the password applies on your other devices too.
7. **Test the password.** Close the presentation, then open it again from Finder. Keynote should ask for the password before it shows any slides. If the file opens without asking, the password was not set, so repeat the steps and check the dialog.

A Keynote password works on the file itself. Keynote scrambles the presentation so nobody can open it without the password. That is different from a slideshow password, which only controls whether people can leave a show you run. This page covers both, plus what to do when a password goes missing.

## Set a password on a Keynote presentation on Mac

Keep the presentation open in Keynote and make sure its window is in front. The steps below follow Apple's Keynote guide for Mac. Apple's password pages do not name a Keynote version, so check yours under Keynote > About Keynote before you follow them.

## What the Set Password dialog asks for

Apple's guide says the dialog asks for the requested information. Expect a password, a confirmation, and one checkbox. The checkbox you see depends on whether Touch ID is set up on the Mac. That checkbox changes what happens later, so read it before you click.

| Checkbox | When you see it | What it does for you |
| --- | --- | --- |
| Open with Touch ID | Touch ID is set up on this Mac | Lets you open the protected file with your fingerprint |
| Remember this password in my keychain | Touch ID is not set up on this Mac | Stores the password in Keychain Access, so you can look it up later |

_The checkbox you see depends on Touch ID setup._

Here is the catch. Apple says a forgotten presentation password cannot be recovered. The keychain entry is the only documented way to get a password back, and it exists only if you ticked that box. Decide on the checkbox before you set the password, not after.

## Set up Touch ID to open a protected presentation

Touch ID saves you from typing the password on a Mac you use every day. You set it up once in System Settings, then turn it on in Keynote. Do this before you set the file password, so the Open with Touch ID checkbox appears.

1. Open System Settings and click Touch ID & Password.
2. Click Add Fingerprint and follow the prompts.
3. In Keynote, choose Keynote > Settings and select Use Touch ID.
4. Double-click the protected presentation and use Touch ID to open it.

## Change or remove a Keynote presentation password

Changing and removing a password both start in the same menu, File > Change Password. Type the old password first. To change it, enter the new password and click Change Password. To remove it, click Remove Password instead.

| Task | Menu path | What to enter | Button to click |
| --- | --- | --- | --- |
| Set a password | File > Set Password | The password and any requested fields | Set Password |
| Change a password | File > Change Password | Old password, then new password | Change Password |
| Remove a password | File > Change Password | Old password | Remove Password |

_Menu paths and buttons as Apple's Mac guide lists them._

Removing a password only changes who can open the file. Close the presentation and reopen it to confirm the prompt is gone. If you still see a prompt, the removal did not finish, so repeat the steps and watch for the confirmation.

## Slideshow exit password: a separate setting

A file password and a slideshow exit password do different jobs. The file password decides who can open the presentation. The exit password decides whether someone in the room can leave a slideshow you run. Apple's guide treats the exit password as its own setting.

Turn it on under Keynote > Settings, then open the Slideshow tab. Select Require password to exit slideshows, enter a password, and click Set Password. The setting applies only to slideshows played on the Mac where you set it. If you present from a different Mac, set it there too.

## Passwords in iCloud Drive and Keynote for iCloud

If you keep the presentation in iCloud Drive, the password follows the file. Apple says a password added on one device is then required on all your devices. Plan for that before you lock a file you open on another Mac, an iPad, or an iPhone.

Keynote for iCloud has its own menu. Click More, then Set Password, enter the password and a hint, and confirm. To change or remove it, click More, then Change Password, and enter the old password first. Apple's help page does not say whether a protected file opens in the browser, so test that before you present from one.

## Sharing a password-protected presentation

A presentation has only one password. If you change it while the file is shared, the new password replaces the original. Collaborators with edit access can add, change, or delete the password. Anyone who still has an older copy may hold the old password.

To block that access, stop sharing, add a unique password, then share the file again. This takes a minute, and it is the only step Apple describes for closing off older versions.

## What to do if you forget the password

Apple says there is no way to recover a forgotten Keynote presentation password. That is the hard part, and it is why the steps above ask you to pick one you will remember. The only documented route is the Keychain entry, and it works only when the keychain box was ticked and Touch ID was not set up.

A 2020 iDownloadBlog guide describes how to find the saved entry. Apple's own pages do not describe this route. The article shows how to read a password you saved, not how to get around one. It may not match current macOS, so treat it as a last resort.

1. Open Keychain Access from Applications > Utilities.
2. Click Passwords in the login section.
3. Find the entry for your presentation and double-click it.
4. Tick Show Password and enter your Mac user password.

> **Write it down first:** Apple cannot reset a forgotten presentation password. Save it in a password manager before you click Set Password, then check that you can read it back.

## Mistakes people make with Keynote passwords

- Choosing a password you will forget. Apple cannot recover it, so there is no reset option.
- Skipping the keychain or Touch ID box, then losing the only documented way back in.
- Confusing the file password with the slideshow exit password. They are separate settings.
- Changing the password during a share and assuming old copies stop working.
- Sending the password in the same email as the file. Send it on a separate channel.
- Forgetting that a password added on one device is required on your other iCloud devices.

## Worked example: locking a pitch deck before you send it

Say you finish a pitch deck on Friday and send it to a client on Monday. You open the final file and choose File > Set Password. You type a passphrase of four unrelated words, and you tick Remember this password in my keychain, because this Mac has no Touch ID set up.

You click Set Password, then save with ⌘S. Next, you close the file and reopen it from Finder to confirm the prompt appears. You send the password in a separate message, not in the email with the file.

## Which Keynote version and plan you need

Apple's What's new page lists Keynote 15.4 as the latest Mac version. It requires macOS 26 or later. Apple's password pages do not state a version, so confirm yours before you follow the menus.

Apple released Keynote 15.1 on January 28, 2026, as part of Apple Creator Studio. MacRumors reports that the older Mac app was updated to 14.5 only to say it no longer gets new features. The Creator Studio app installs separately. Apple's guides do not say which app their password steps refer to, so check which Keynote you opened.

Creator Studio costs $12.99 a month or $129 a year in the U.S. New subscribers get a one-month free trial. Apple's newsroom also says Keynote stays free for everyone to create, edit and collaborate, including Creator Studio subscribers.

## Test the lock before you present

Test the presentation on the Mac you will present from. Close it, reopen it, and confirm the password prompt appears. Then play the slideshow and check the exit password if you set one. Do this a day early, not in the meeting room.

## Shortcuts

- Open a presentation (standard macOS): ⌘O
- Save the presentation (standard macOS): ⌘S

## If it does not work

- **Set Password does not appear in the File menu** Make sure the presentation window is active and in front. Click the slide canvas, then open the File menu again. If the file is a PDF or another format, open the original presentation in Keynote.
- **No Open with Touch ID checkbox appears** Touch ID is not set up on this Mac, so Keynote shows Remember this password in my keychain instead. Set up Touch ID in System Settings first, then set the password.
- **The file opens without asking for a password** The password was not set. Open the file, choose File > Set Password, and repeat the steps. If the file already has a password, use File > Change Password instead.
- **I forgot the presentation password** Apple says it cannot be recovered. Check Keychain Access for a saved entry, but only if you ticked the keychain box and Touch ID was not set up. If there is no entry, Apple's steps offer no other route.
- **An old password still works on a shared copy** Changing the password does not block older copies. Stop sharing, add a unique password, then share the file again.
- **The audience can leave a slideshow I run** Set Require password to exit slideshows in Keynote > Settings > Slideshow, on the Mac you present from. The setting does not carry over to other Macs.
