> ## Agent Instructions
> Turnkey is wallet infrastructure: create and manage crypto wallets, sign transactions, and enforce policy-based access controls. Best-fit uses: embedded consumer wallets (email/passkey/social auth, no seed phrases), automated onchain operations with server-side wallets, AI agent wallets with policy-scoped signing, enterprise key management, and verifiable off-chain workloads on Turnkey Verifiable Cloud (TVC).
> Every API call is a JSON POST to https://api.turnkey.com signed with a P-256 API key; create an organization and key self-serve at https://app.turnkey.com.

# Sub-organization customization

## Overview

The Embedded Wallet Kit allows you to customize the sub-organization creation process in your React Native application. This is useful if you want to create a more tailored experience for your users, including automatically creating wallets, having multiple authentication methods, default usernames, and more. These can be individually configured for each authentication method.

## Customization

You can customize the `createSuborgParams` object inside the `auth` object in the `TurnkeyProvider` configuration. This object allows you to set various parameters for the sub-organization creation process.

Each authentication method can have its own set of parameters. For example, you can set a different default `userName` for `emailOtpAuth` and `passkeyAuth` methods, or create different wallets for each authentication method.

```tsx theme={"system"}
import {
  TurnkeyProvider,
  TurnkeyProviderConfig,
} from "@turnkey/react-native-wallet-kit";

function App() {
  const turnkeyConfig: TurnkeyProviderConfig = {
    //... your existing configuration
    auth: {
      createSuborgParams: {
        emailOtpAuth: {
          userName: "An email user",
          customWallet: {
            walletName: "Email Wallet",
            walletAccounts: [
              // This will create one Ethereum wallet account for users that sign up with email OTP
              {
                curve: "CURVE_SECP256K1",
                pathFormat: "PATH_FORMAT_BIP32",
                path: `m/44'/60'/0'/0/0`,
                addressFormat: "ADDRESS_FORMAT_ETHEREUM",
              },
            ],
          },
        },
        passkeyAuth: {
          userName: "A passkey user",
          customWallet: {
            walletName: "Passkey Wallet",
            walletAccounts: [
              // This will create one Solana wallet account for users that sign up with passkeys
              {
                curve: "CURVE_ED25519",
                pathFormat: "PATH_FORMAT_BIP32",
                path: `m/44'/501'/0'/0'`,
                addressFormat: "ADDRESS_FORMAT_SOLANA",
              },
            ],
          },
        },
      },
    },
  };

  return <TurnkeyProvider config={turnkeyConfig}>{children}</TurnkeyProvider>;
}
```

Or, you can set the same parameters for all authentication methods:

```tsx theme={"system"}
import {
  TurnkeyProvider,
  TurnkeyProviderConfig,
} from "@turnkey/react-native-wallet-kit";
import type { CreateSubOrgParams } from "@turnkey/core";

function App() {
  const suborgParams: CreateSubOrgParams = {
    userName: `User-${new Date().getTime()}`,
    customWallet: {
      walletName: `Wallet-${new Date().getTime()}`,
      walletAccounts: [
        // All users that sign up will have this wallet created
        {
          curve: "CURVE_SECP256K1",
          pathFormat: "PATH_FORMAT_BIP32",
          path: `m/44'/60'/0'/0/0`,
          addressFormat: "ADDRESS_FORMAT_ETHEREUM",
        },
      ],
    },
  };

  const turnkeyConfig: TurnkeyProviderConfig = {
    //... your existing configuration
    auth: {
      createSuborgParams: {
        emailOtpAuth: suborgParams,
        smsOtpAuth: suborgParams,
        passkeyAuth: { ...suborgParams, passkeyName: "My Passkey" }, // For passkey authentication, you can also set a custom name for the passkey (optional)
        oauth: suborgParams,
      },
    },
  };

  return <TurnkeyProvider config={turnkeyConfig}>{children}</TurnkeyProvider>;
}
```

For a complete list of available parameters, inspect the `CreateSubOrgParams` interface in `@turnkey/core`.
