Sign-in links now work from your email app

Tapping the sign-in link in your email now signs you in, whichever app or browser opens it.

What's new

Signing in or creating an account sends you an email with a link. Until now, tapping that link on a phone confirmed your email but often didn't sign you in, because the email app opened the link in a different browser from the one you started in. The link now signs you in wherever it opens. A link that has expired or was already used says so and offers to send a new one.

Behind the scenes

  • Sign-in links carry the session back to a new page, /auth/confirm, which hands it to our server to store as your sign-in cookie and then clears it from the address bar.
  • Sign-in cookies can no longer be read by scripts on the page; only our server reads them.
  • The site's sign-in settings now point at the live address. They had pointed at an address that needs a Vercel login.
