Radically Simple.

It only takes one line of code.

<SignIn />

Your sign-in flow is the only thing sitting between existing users and your application—it's absolutely critical that users can complete the process quickly.

import { SignIn } from '@clerk/nextjs';
  ...
    return (
      <>
        <BackgroundImage />
        <SignIn />
      </>
    );
  ...

<UserProfile />

A place for your users to change their password, turn on multifactor auth, revoke bad sessions, and more. Every app should offer the best security options, so every user can be safe.

import { UserProfile } from '@clerk/nextjs';
  ...
    return (
      <>
        <CustomHeader />
        <UserProfile />
      </>
    );
