Sure, you can definitely use your own custom UI with Ory Kratos. Here are the steps you need to follow: 1. Define the paths where Ory calls your custom UI: You can do this by going to [Ory Console](https://console.ory.sh/) → User Interface. This view allows you to define the URLs of UI views for every self-service flow. You can use relative or absolute paths. If you don't set a custom UI base URL, relative links will use your SDK Configuration URL as the base. You can check your SDK Configuration URL by going to [Ory Console](https://console.ory.sh/) → Access & APIs. [source](https://www.ory.sh/docs/kratos/bring-your-own-ui/configure-ory-to-use-your-ui) 2. Implement your custom UI: You can use Ory Elements, a component library designed to make building login, registration, and account pages for Ory straightforward. Ory Elements is modular and customizable, which means that you can use only the views you need and style them to match your implementation's design. The UI created with Ory Elements changes dynamically to adapt to your Ory Network configuration. [source](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-ory-elements) 3. Create an API flow with return_session_token_exchange_code=true: The user opens the login screen and the native application initializes a login or registration flow through the Ory Network APIs with the following parameters: - The flow is of type

api

. - The

return_to

parameter is set to the URL of the native application. This URL is used to redirect the user back to the app after the social sign-in. - The

return_session_token_exchange_code

parameter is set to

true

to receive the session token exchange code in the response. [source](https://www.ory.sh/docs/kratos/social-signin/native-apps#implementation) 4. Handle the registration and login flows: Your custom UI should be able to handle the registration and login flows. This involves getting the registration or login flow (if it exists in the URL) or fallback to start the registration or login flow to get the

flow

data on page load. Then, submit the registration or login form data the user provides when they click the Submit button. [source](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-ory-elements#registration) Please note that the code examples provided in the documentation are written in TypeScript for React Native. You may need to adjust them to fit your TypeScript backend.
