# Auth forms (Better Auth client, not Superforms)

> Generated from `mcp/patterns.registry.json` — do not edit by hand; change the registry and run `bun run patterns:build`.

_Index card — the docs below are the canonical explanation; deep-tier pattern pages additionally carry invariants and emulation notes._

**Category:** Forms & Validation · **Tier:** light · **Risk:** medium — authentication flow, delegated to Better Auth client

Passwordless login (magic link + OTP) and OAuth forms built directly on the Better Auth client instead of Superforms, since Better Auth already handles rate limiting and token validation.

**When to use:** Use for any authentication entry point (email login, OTP verification, OAuth) instead of wiring the flow through Superforms.
