Intro to collaboration in Pages for iCloud
You can collaborate with others in real time by sharing a link to your Pages for iCloud document. Shared documents and any changes to them are saved in iCloud, and people working in the document see the changes as they’re made.
As the owner of the document, you control who can open it, and what they can do:
Document access: You can send a link that anyone can use to open the document. Or, you can invite specific people who must sign in with their Apple ID to open the document.
Editing permission: You can choose whether others can make changes to the document or only view it.
If you set access to allow anyone with the link to open your document, they don’t need an iCloud account or Apple ID to view or edit the shared document.
If you invite specific people to collaborate on your document, they must be signed in with their Apple ID and have iCloud Drive turned on to view or edit the document. 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. See Accept an invitation to collaborate.
Minimum system requirements
To view or edit a shared document, people you share with need any of the following:
A Mac with macOS High Sierra 10.14 or later and Pages 10.0 or later
An iPhone with iOS 12 or later and Pages 10.0 or later
An iPad with iOS 12, iPadOS 13, or later and Pages 10.0 or later
A Mac or Windows computer with a supported browser
On an Android device, or a device without iOS 12, iPadOS 13, or later and Pages 10.0 or later, people can view, but not edit, the document.
If your document is stored in Box instead of iCloud, you can still collaborate using the collaboration controls in Box. See the Apple Support article on using iWork with Box.
