`<SignIn />` component

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, 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.

Note

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.

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.

Next.js

React

Remix

Gatsby

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>;
}

/src/sign-in/[[...index]].tsx

import { SignIn } from "@clerk/clerk-react";

const SignInPage = () => (
  <SignIn path="/sign-in" routing="path" signUpUrl="/sign-up" />
);

export default SignInPage;

app/routes/sign-in/$.tsx

import { SignIn } from "@clerk/remix";

export default function SignInPage() {
  return (
    <div style={{ border: "2px solid blue", padding: "2rem" }}>
      <h1>Sign In route</h1>
      <SignIn routing={"path"} path={"/sign-in"} />
    </div>
  );
}

/pages/sign-in.js

import { SignIn } from "gatsby-plugin-clerk";

export default function SignInPage() {
  return (
    <div style={{ border: "2px solid blue", padding: "2rem" }}>
      <h1>Sign In Up route</h1>
      <SignIn routing={"path"} path={"/sign-in"} />
    </div>
  );
}
