Examples

Login route

Render the sign-in form on a login page.

login-route.tsx
import { LoginForm } from '@/registry/default/blocks/password-based-auth-react/components/login-form'export default function LoginPage() {  return <LoginForm className="mx-auto w-full max-w-md" />}

Registration route

Render the sign-up form on an account creation page.

registration-route.tsx
import { SignUpForm } from '@/registry/default/blocks/password-based-auth-react/components/sign-up-form'export default function SignUpPage() {  return (    <main className="flex min-h-screen items-center justify-center p-6">      <SignUpForm className="w-full max-w-md" />    </main>  )}

Password recovery routes

Use the forgot-password form to request an email and the update-password form after the recovery link is opened.

password-recovery-routes.tsx
import { ForgotPasswordForm } from '@/registry/default/blocks/password-based-auth-react/components/forgot-password-form'import { UpdatePasswordForm } from '@/registry/default/blocks/password-based-auth-react/components/update-password-form'export function ForgotPasswordPage() {  return <ForgotPasswordForm className="mx-auto w-full max-w-md" />}export function UpdatePasswordPage() {  return <UpdatePasswordForm className="mx-auto w-full max-w-md" />}

API reference

PropTypeDefaultDescription
LoginForm propsReact.ComponentPropsWithoutRef<'div'>—Accepts all non-ref React props for a div, including className and arbitrary div attributes. className is merged with the component's flex-column layout classes; remaining props are spread onto the root div.
SignUpForm propsReact.ComponentPropsWithoutRef<'div'>—Accepts all non-ref React props for a div, including className and arbitrary div attributes. className is merged with the component's flex-column layout classes; remaining props are spread onto the root div.
ForgotPasswordForm propsReact.ComponentPropsWithoutRef<'div'>—Accepts all non-ref React props for a div, including className and arbitrary div attributes. className is merged with the component's flex-column layout classes; remaining props are spread onto the root div.
UpdatePasswordForm propsReact.ComponentPropsWithoutRef<'div'>—Accepts all non-ref React props for a div, including className and arbitrary div attributes. className is merged with the component's flex-column layout classes; remaining props are spread onto the root div.

Accessibility

  • Each form input has a visible Label associated with its input through matching htmlFor and id values.
  • Email fields use type="email" and all password and email fields are required, enabling browser validation and appropriate input semantics.
  • Submit buttons expose disabled state while requests are in progress and change their text to communicate the current operation.
  • Authentication errors are rendered as visible text in the form.
  • The components do not add aria-live, aria-invalid, or aria-describedby attributes to error messages, so applications needing announced validation errors should add that behavior.
  • Navigation uses standard anchor elements for login, sign-up, and forgot-password routes.
  • The repeated id values are safe when each form is rendered on its own page; avoid rendering multiple instances of the same form on one page without adjusting IDs.
