Yardline Lets Crews Confirm Deliveries via Secure, No-Login Links

Yardline, a tool for handling handoffs between building suppliers and contractors, lets crew leads on site confirm deliveries without creating an account. Instead, the office sends the crew a link by text message that opens a single delivery, where they can check the contents, note missing or damaged items, and mark it received. The design treats the link as a secure, expiring credential: tokens are 256-bit random values, only their SHA-256 hashes are stored, and links expire within one to 30 days by default after seven. Offices can revoke links at any time, and actions taken through them are logged under a separate guest identity rather than the office user who created the link. Search engines are also barred from indexing the pages, and each request revalidates the token.
