Invite others to collaborate in Keynote on iPhone
You can invite others to work with you on a presentation in real time by sending them a link to it. Everyone working on the presentation can see changes as they’re made.
By default, only the people you invite to collaborate on the presentation can access and make changes to it. You can also change permissions to allow:
Anyone who has the link to access the presentation
View-only permission, so others cannot make changes
Participants can also present a shared slideshow with you. To learn more about multipresenter slideshows, see Play a slideshow with multiple presenters.
Invite people to collaborate
To invite others to collaborate on a presentation, you must first store the presentation in iCloud. Make sure that you’re signed in with your Apple ID and that Keynote is set up to use iCloud Drive.
Do one of the following:
If the presentation is open: Tap
. If you don’t see the button, tap 
at the top of the screen, then tap .If the presentation is closed: In the presentation manager or Files app, open the Keynote folder in iCloud Drive, tap
in the top-right corner, then tap Select. Tap the presentation (a checkmark appears), then tap at the bottom of the screen.
If the presentation isn’t stored in iCloud Drive, follow the prompt to move it there.
Below Who Can Access, tap an option:
People you invite: Only people you invite who sign in with their Apple ID can open the presentation. People don’t need to have an Apple ID before you invite them; however, they need to create one before they can open your shared presentation.
Anyone with the link: Anyone who has the link to the shared presentation can tap or click the link to open the presentation. To protect it with a password, tap Add Password.
If this presentation already has a password, it applies to the shared presentation as well, so you don’t need to enter a new one. If you want to change it, tap Change Password.
Below Permission, tap an option to set what others can do:
Can make changes: People can edit and print the shared presentation.
View only: People can view and print the shared presentation but not edit it.
If you set access to “People you invite” (in the previous step), you can change an individual’s settings after you share the presentation.
If you have iPadOS 15 or later installed, and you don’t want all participants to be able to invite others, turn off “Anyone can add more people.”
Tap Add People.
Tap a method for sending the link.
AirDrop: Use AirDrop when your recipient’s on the same network and able to accept the presentation. Select the person you want to send the presentation to. The recipient must accept the file to receive it.
Mail or Messages: Mail and Messages both send a copy directly to one or more email addresses or phone numbers and can be accompanied with a custom note. Type an email address or phone number for each participant. If you invite someone using an email address or phone number that isn’t associated with their Apple ID, they won’t be able to accept the invitation until they add the email address or phone number to their Apple ID. When they tap or click the link in the invitation, instructions appear. The link appears in the body of the message along with the presentation title.
Important: Make sure not to edit or delete the link in your message.
Copy Link: Copy the presentation’s link so you can easily send, post, or access it. You can send the link using any internet service that’s already set up on your device. Tap where you want to paste the link, then tap Paste.
Important: The link to the presentation that’s created when you tap Share includes the presentation’s title. If the title or content of the presentation is confidential, be sure to ask recipients not to forward the link to anyone else.
When you send the invitation, a checkmark appears on the Collaborate button 
to indicate you’ve shared the presentation.
Invite more people
Depending on how you set presentation access, you can invite more people to collaborate on your file by adding them or by sending a link.
Tip: If the presentation is protected by a password, for security reasons don’t send the password with the link.
Do one of the following:
If the presentation is open: Tap
, then tap Manage Shared Presentation.If the presentation is closed: In the presentation manager or Files app, open the Keynote folder in iCloud Drive, tap
in the top-right corner, tap Select, tap the presentation (a checkmark appears), then tap at the bottom of the screen.
Do one of the following:
Invite more people to collaborate: Use this method if you’re the owner of a shared presentation with access set to “People you invite,” or if the presentation owner gave you permission to add more people. Tap Add People, tap a method to invite your new participant, then tap Share. See Invite people to collaborate.
Send the link to more people: Use this method if presentation access is set to “Anyone with the link.” Tap Copy Link, tap where you want to paste the link, then tap Paste.
Tip: You can also post the shared link on a website that supports embedded Keynote presentations (such as Medium or WordPress) so that viewers can navigate through the presentation in a player on the website. See Post your presentation in a blog with Keynote on iPhone.
Note: The link may appear in the body of the message as a stylized graphic with the presentation title—be sure not to edit or delete it.
Any participant can copy a link to a presentation and paste it somewhere else—for example, to save the link where they can easily access it. If the owner limited access to people they invite, the link only works for invited participants.
You can change the sharing settings for the new people after you send the link.
