Got it. So for customisation of CSS, you can see https://supertokens.io/docs/emailpassword/common-customizations/styling/changing-style To embed a component in your existing page, you can see: 1) https://supertokens.io/docs/emailpassword/common-customizations/embed-sign-in-up-form 2) https://supertokens.io/docs/emailpassword/common-customizations/reset-password/embed-in-page 3) https://supertokens.io/docs/emailpassword/common-customizations/email-verification/embed-in-page To slit the sign in and sign up component into two, is a little bit more complex, but possible. What you want to do is to render the

<SignInAndUp/>

in two pages, then you want to use the react component override feature (https://supertokens.io/docs/emailpassword/advanced-customizations/react-component-override/usage) to override

EmailPasswordSignUp

and

EmailPasswordSignIn

component, and render the original component based on the current website path, otherwise return

null

(hence not displaying the component). This way, you will see the sign in page in one path, and sign up page in another path.
