Step by step
Put what you want to share in a folder
Shares are made from folders. Anything you add to the folder later is shared too.
Choose Share Folder
Give the share a title the recipient will recognise, then pick an expiry and how many times it may be opened.
Send the ten-word phrase
Use an end-to-end encrypted messenger, or read it out in person or on a call. Avoid email and SMS.
The recipient opens it
In their own vault they choose Open Share… and type the phrase. The folder appears under Shared with Me.
Keep an eye on it
Vault Settings lists your shares under Shared by Me, with their expiry and remaining opens.
Revoke when you are done
Revoking removes the share from iCloud. It cannot be opened again.
Know the limits
Expiry and open counts are enforced by the app, not by mathematics. A recipient can still photograph their screen. Share only with people you trust. More in Secure Sharing.
