Measured entry

shadcn-block-login-02

auth-formminimal-flat

A responsive sign-in page that pairs a compact email and password form with a large cover image on wider screens. It ships as a shadcn registry block and depends on the shadcn button, input, label, and field primitives, the shared class-name utility, Tailwind theme classes, and a Lucide icon.

Verdict

A sensible starter for a familiar branded login page, with clean responsive behavior and no detected accessibility violations. It needs a shadcn-style setup, real navigation and auth wiring, and a replacement for the unresolved placeholder image before production use.

Use it if

  • You already use shadcn conventions and want a conventional email and password login shell.
  • You want a split-screen auth page whose cover panel drops away on narrower screens.
  • You plan to connect the form, recovery link, signup link, and GitHub button to your own auth flow.

Skip it if

  • Your project does not use Tailwind or shadcn primitives and you do not want to recreate their styling contract.
  • You need working authentication, validation, error states, or social OAuth out of the box.
  • You cannot supply and maintain a real cover asset, since the included placeholder path does not resolve in the tested mount.
  • Your product should avoid decorative split-screen imagery in favor of a smaller, content-only login surface.

Providerno provider required in the harness

In a non-shadcn project, add compatible button, input, label, and field components, a class-name merging helper, the expected Tailwind theme tokens and utilities, and the Lucide icon package. Remap the registry aliases, provide a cover image, and connect submit and link behavior to your authentication system.
