## Best for

A magic link sign-in beside a twinkling dot field holding 1 quote with 5 stars and 4 trust wordmarks

## Agent notes

- Replace `AUTH3_TESTIMONIAL` and the 4 wordmarks in `AUTH3_TRUST_BRANDS`, both rendered by `Sidebar` in auth.tsx
- The 15 minute expiry under Work email is fixed `FieldDescription` copy; match it to your magic link lifetime
- `WaveDots` redraws its canvas on every `requestAnimationFrame`; tune `GAP`, `SPEED` and `PEAK` at the top of its effect

## When not to use

- A password form with its quote and logos panel on the left, over a square grid: use [Social Proof Login](https://web.dev.reui.io/blocks/application/auth/auth-18.md) (`get_block("auth-18")`)
- A full-height photo panel on the left in place of the quote: use [Photo Magic Link](https://web.dev.reui.io/blocks/application/auth/auth-13.md) (`get_block("auth-13")`)

## Install

```bash
npx shadcn@latest add @reui/auth-3
```

## 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
