<SignIn /> component

Sign in component example

The <SignIn /> component renders a UI for signing in users. The functionality of the <SignIn /> component is controlled by the instance settings you specify in your Clerk Dashboard(opens in a new tab), such as sign-in and sign-up options and social connections. You can further customize your <SignIn /> component by passing additional properties at the time of rendering.

The <SignUp/> and <SignIn/> components cannot render when a user is already signed in, unless the application allows multiple sessions. If a user is already signed in and the application only allows a single session, Clerk will redirect the user to the Home URL instead.

Properties

Usage with frameworks

The following example includes basic implementation of the <SignIn /> component. You can use this as a starting point for your own implementation.

The following example demonstrates how you can use the <SignIn /> component on a public page.

If you would like to create a dedicated /sign-in page in your Next.js application, check out the dedicated guide..

app/page.tsx
import { SignIn, useUser } from "@clerk/nextjs"; export default function Home() { const { user } = useUser(); if (!user) { return <SignIn />; } return <div>Welcome!</div>; }
