## Best for

A bare magic link page with the logo on top and a legal consent, copyright, Docs and Support footer

## Agent notes

- Replace `AUTH15_SOCIAL_PROVIDERS` and `AUTH15_FOOTER_LINKS` in data.tsx; every footer link `href` is a placeholder #
- `LoginForm` hardcodes ReUI in the Terms and Conditions consent line and the 2026 copyright; put your company name there
- The `auth-15-email` input has no name attribute, so `handleSubmit` cannot read the address from form data yet

## When not to use

- A password login card with a show password toggle and a forgot password link: use [Centered Password Login](https://web.dev.reui.io/blocks/application/auth/auth-20.md) (`get_block("auth-20")`)
- Access limited to approved workspace emails, with a request invite link up top: use [Invite-Only Sign-In](https://web.dev.reui.io/blocks/application/auth/auth-19.md) (`get_block("auth-19")`)

## Install

```bash
npx shadcn@latest add @reui/auth-15
```

## 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
