Measured entry

shadcn-block-login-05

auth-formminimal-flat

A centered email-only sign-in screen shipped as a shadcn registry page plus a reusable React form. It includes placeholder Apple and Google actions, account and legal links, and depends on shadcn field, button, input, and label conventions, the cn utility, Lucide icons, Tailwind theme classes, and Radix UI.

Verdict

A clean, responsive starting point for an email-first auth screen, with no reported runtime or accessibility issues in the configured harness. It is presentation only, and the bare mount fails because it needs a shadcn-style setup with the expected utilities, components, aliases, and theme.

Use it if

  • You need a compact email-first login page with optional social sign-in choices.
  • Your app already uses shadcn components, Tailwind theme tokens, and aliased imports.
  • You want an accessible responsive shell and will connect the form and links to your own authentication flow.

Skip it if

  • You need a password field, validation feedback, recovery links, or authentication logic out of the box.
  • Your design system does not use shadcn component APIs or Tailwind utility classes.
  • You cannot replace placeholder branding, links, and social provider actions before release.

In a non-shadcn project, add the compatible button, input, label, and field components, the cn class-merging utility, Tailwind theme tokens and utilities, the expected import aliases, Lucide React icons, and Radix UI. Then wire submit, social actions, navigation, and legal links to real routes and handlers.
