 Instant Keys are the fastest way to give someone mobile access. When you create an Access Grant with a `mobile_key` access method, Seam automatically generates an Instant Key URL. Share this URL with your user through text, email, or your app. When they tap the link, they can unlock the door immediately — no app download required.
 
 Instant Keys use iOS App Clips and Android Instant Apps to provide a native unlock experience without requiring your user to install anything.
