## Best for

An invite-only workspace sign-in Card with Google and GitHub first and a mail icon email field below

## Agent notes

- `handleSubmit` sits inside `SignInCard`, not the page; send the work email to your magic link endpoint from there
- Request invite in the header is a link `Button` whose `render` anchor points at #; route it to your access request flow
- Replace `AUTH19_PROVIDERS` in data.tsx to change the Google and GitHub buttons above the email field

## When not to use

- A centered card that signs in with a password, with Google and Apple first: use [Centered Password Login](https://web.dev.reui.io/blocks/application/auth/auth-20.md) (`get_block("auth-20")`)
- A split page with a star rated customer quote and trust logos beside the form: use [Social Proof Login](https://web.dev.reui.io/blocks/application/auth/auth-18.md) (`get_block("auth-18")`)

## Install

```bash
npx shadcn@latest add @reui/auth-19
```

## 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
