A fresh alias from the Safari share sheet.

Share any page to the Emcognito alias Shortcut and a new alias, labelled with that site, lands on your clipboard, ready to paste into the sign-up form. Three steps, about two minutes, no App Store download.

  1. 1. Connect your iPhone

    In Settings › Devices, name your iPhone and tap Add iPhone. Copy the token it shows; it is shown once. The token can only create aliases: it cannot read your mail, your aliases, or your account, and you can revoke it there at any time.

    The Devices card in Emcognito settings with a Device name field set to My iPhone and an Add iPhone button
    Settings › Devices: name the phone and tap Add iPhone.
    The Devices card after Add iPhone, showing a token field starting emd_ with a Copy button and a note that it is shown once
    Copy the token now; it is shown once. You can revoke it from the same card.

    Devices are on Plus and Pro. See Plus

  2. 2. Get the Shortcut

    Open the Shortcuts app and tap +. The new shortcut opens on Describe a shortcut; tap Editor for the action editor. Find each action with the Search field at the bottom and add them in this order:

    4. Get Dictionary Value: email from Contents of URL.
    5. Copy to Clipboard: the Dictionary Value.
    6. Show Notification: Copied and the Dictionary Value.

    Finally tap ⓘ, then Details, and turn on Show in Share Sheet.

    The last actions copy the new address and confirm it with a notification.

If something goes wrong

“This iPhone was disconnected”
The token was revoked or mistyped. Add the iPhone again in Settings › Devices and paste the new token into the Shortcut.
“Your plan no longer includes this”
The Shortcut needs Plus or Pro. Your token is kept for 30 days after a move to Free and works again if you upgrade within that time.
“Could not create an alias”
No connection, or a problem on our side. Nothing was copied; try again.

On Android? Install Emcognito from your browser's menu and share to it instead. That is on Plus and Pro from November 3, 2026.
