<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(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

All props are optional.

Name	Type	Description
`appearance`	`Appearance \| undefined`	Optional object to style your components. Will only affect Clerk Components and not Account Portal pages.
`routing`	`'hash' \| 'path' \| 'virtual'`	The routing strategy for your pages. Defaults to `'path'`.
`path`	`string`	The path where the component is mounted on when path-based routing is used. This prop will be required for Next.js and Remix applications that do not set the appropriate environment variables, and is required for all other SDK's. This prop is ignored in hash- and virtual-based routing.
`redirectUrl`	`string`	Full URL or path to navigate after successful sign in or sign up. The same as setting `afterSignInUrl` and `afterSignUpUrl` to the same value.
`afterSignInUrl`	`string`	The full URL or path to navigate after a successful sign in. Defaults to `/`. It's recommended to use the environment variable instead.
`signUpUrl`	`string`	Full URL or path to the sign up page. Use this property to provide the target of the 'Sign Up' link that's rendered. It's recommended to use the environment variable instead.
`afterSignUpUrl`	`string`	The full URL or path to navigate after a successful sign up. Defaults to `/`. It's recommended to use the environment variable instead.
`initialValues`	`SignInInitialValues`	The values used to prefill the sign-in fields with.

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.

/app/sign-in/[[...sign-in]]/page.tsx
  import { SignIn } from "@clerk/nextjs";
 
  export default function Page() {
    return <SignIn path="/sign-in" signUpUrl="/sign-up" />
  };

You will notice a path prop is being passed to the SignIn /> component. This is because, by default, the routing strategy is set to path, requiring the path prop to be passed. In Next.js applications, you can either pass the path prop to the <SignIn /> component, or you can define the NEXT_PUBLIC_CLERK_SIGN_IN_URL and NEXT_PUBLIC_CLERK_SIGN_UP_URL environment variables.

The example below shows how to mount the <SignIn /> component on a page without a path prop. Select the .env.local tab to see an example of how to define the appropriate environment variables.

/app/sign-in/[[...sign-in]]/page.tsx
import { SignIn } from "@clerk/nextjs";
 
```tsx filename="app/page.tsx"
import { SignIn, useUser } from "@clerk/nextjs";
 
export default function Home() {
const { user } = useUser();
 
if (!user) {
  return <SignIn />;
}
 
```env filename=".env.local"
NEXT_PUBLIC_CLERK_SIGN_IN_URL=/sign-in
NEXT_PUBLIC_CLERK_SIGN_UP_URL=/sign-up

/src/sign-in/[[...index]].tsx
import { SignIn } from "@clerk/clerk-react";
 
const SignInPage = () => (
  <SignIn path="/sign-in" />
);
 
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 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 path="/sign-in" />
    </div>
  );
}

Usage with JavaScript

The following methods available on an instance of the Clerk class are used to render and control the <SignIn /> component:

The following examples assume that you have followed the quickstart in order to add Clerk to your JavaScript application.

Render the <SignIn /> component to an HTML <div> element.


function mountSignIn(node: HTMLDivElement, props?: SignInProps): void;

Name	Type	Description
`node`	`HTMLDivElement`(opens in a new tab)	The container `<div>` element used to render in the `<SignIn />` component
`props?`	`SignInProps`	The properties to pass to the `<SignIn />` component

index.js
import Clerk from "@clerk/clerk-js";
 
// Initialize Clerk with your Clerk publishable key
const clerk = new Clerk("{{pub_key}}");
await clerk.load();
 
document.getElementById("app").innerHTML = `
  <div id="sign-in"></div>
`;
 
const signInDiv = document.getElementById("sign-in");
 
clerk.mountSignIn(signInDiv);

index.html
<!-- Add a <div id="sign-in"> element to your HTML -->
<div id="sign-in"></div>
 
<!-- Initialize Clerk with your
Clerk Publishable key and Frontend API URL -->
<script
  async
  crossorigin="anonymous"
  data-clerk-publishable-key="{{pub_key}}"
  src="https://{{fapi_url}}/npm/@clerk/clerk-js@latest/dist/clerk.browser.js"
  type="text/javascript"
></script>
 
<script>
  window.addEventListener("load", async function () {
    await Clerk.load();
 
    const signInDiv = document.getElementById("sign-in");
 
    Clerk.mountSignIn(signInDiv);
  });
</script>

Unmount and run cleanup on an existing <SignIn /> component instance.


function unmountSignIn(node: HTMLDivElement): void;

Name	Type	Description
`node`	`HTMLDivElement`(opens in a new tab)	The container `<div>` element with a rendered `<SignIn />` component instance

index.js
import Clerk from "@clerk/clerk-js";
 
// Initialize Clerk with your Clerk publishable key
const clerk = new Clerk("{{pub_key}}");
await clerk.load();
 
document.getElementById("app").innerHTML = `
  <div id="sign-in"></div>
`;
 
const signInDiv = document.getElementById("sign-in");
 
clerk.mountSignIn(signInDiv);
 
// ...
 
clerk.unmountSignIn(signInDiv);

index.html
<!-- Add a <div id="sign-in"> element to your HTML -->
<div id="sign-in"></div>
 
<!-- Initialize Clerk with your
Clerk Publishable key and Frontend API URL -->
<script
  async
  crossorigin="anonymous"
  data-clerk-publishable-key="{{pub_key}}"
  src="https://{{fapi_url}}/npm/@clerk/clerk-js@latest/dist/clerk.browser.js"
  type="text/javascript"
></script>
 
<script>
  window.addEventListener("load", async function () {
    await Clerk.load();
 
    const signInDiv = document.getElementById("sign-in");
 
    Clerk.mountSignIn(signInDiv);
 
    // ...
 
    Clerk.unmountSignIn(signInDiv);
  });
</script>

Opens the <SignIn /> component as an overlay at the root of your HTML body element.


function openSignIn(props?: SignInProps): void;

Name	Type	Desciption
`props?`	`SignInProps`	The properties to pass to the `<SignIn />` component

index.js
import Clerk from "@clerk/clerk-js";
 
// Initialize Clerk with your Clerk publishable key
const clerk = new Clerk("{{pub_key}}");
await clerk.load();
 
clerk.openSignIn();

index.html
<!-- Initialize Clerk with your
Clerk Publishable key and Frontend API URL -->
<script
  async
  crossorigin="anonymous"
  data-clerk-publishable-key="{{pub_key}}"
  src="https://{{fapi_url}}/npm/@clerk/clerk-js@latest/dist/clerk.browser.js"
  type="text/javascript"
></script>
 
<script>
  window.addEventListener("load", async function () {
    await Clerk.load();
 
    Clerk.openSignIn();
  });
</script>

Closes the sign in overlay.


function closeSignIn(): void;

index.js
import Clerk from "@clerk/clerk-js";
 
// Initialize Clerk with your Clerk publishable key
const clerk = new Clerk("{{pub_key}}");
await clerk.load();
 
clerk.openSignIn();
 
// ...
 
clerk.closeSignIn();

index.html
<!-- Initialize Clerk with your
Clerk Publishable key and Frontend API URL -->
<script
  async
  crossorigin="anonymous"
  data-clerk-publishable-key="{{pub_key}}"
  src="https://{{fapi_url}}/npm/@clerk/clerk-js@latest/dist/clerk.browser.js"
  type="text/javascript"
></script>
 
<script>
  window.addEventListener("load", async function () {
    await Clerk.load();
 
    Clerk.openSignIn();
 
    // ...
 
    Clerk.closeSignIn();
  });
</script>
