## Best for

A password login inside page-wide hairline guides with corner squares, beside a twinkling dot quote panel

## Agent notes

- Replace `AUTH11_TESTIMONIAL` and the 4 wordmarks in `AUTH11_TRUST_BRANDS` shown under Trusted by leading teams
- `LoginForm` renders Forgot password and Sign up as link buttons without a handler; wire your reset and signup routes
- `FrameOverlay` draws its hairlines and `CornerDot` squares at an inset set by CSS variables on the `Auth` root; change the inset there

## When not to use

- A testimonial panel to the left of the form over a square grid, with no page guides: use [Social Proof Login](https://web.dev.reui.io/blocks/application/auth/auth-18.md) (`get_block("auth-18")`)
- Several customer quotes that autoplay in a dark panel above a review rating: use [Customer Quotes Login](https://web.dev.reui.io/blocks/application/auth/auth-2.md) (`get_block("auth-2")`)

## Install

```bash
npx shadcn@latest add @reui/auth-11
```

## About Auth blocks

### When to use

- A full page sign-in screen by password, emailed magic link or passkey, with social provider buttons
- A free trial signup page that opens an account from a work email or a social provider
- A split login layout that pairs the sign-in with a testimonial, a customer logo wall or a photo panel

### When not to use

- A data entry page inside the product, such as intake, invites or sign-in method rules: use the [Form blocks](https://web.dev.reui.io/blocks/application/form.md)
- Security options a signed in admin edits, such as session timeout and access toggles: use the [Settings blocks](https://web.dev.reui.io/blocks/application/settings.md)
- A newsletter or waitlist email capture band on a landing page: use the [CTA blocks](https://web.dev.reui.io/blocks/marketing/cta.md)

### Agent notes

- Each form's submit handler only calls `preventDefault`; call your auth backend from it
- The social and SSO provider buttons have no `onClick`; start your OAuth or SAML redirect from each
- Replace the `AuthLogo` mark in auth-logo.tsx with your own brand logo
