Overview

You can customize how new sub-organizations (and users) are created during signup.
There are three levels of customization:
  1. Global defaults in TurnkeyConfig (applies to all auth methods)
  2. Per-auth-method defaults in TurnkeyConfig
  3. Per-call overrides passed to signup helpers (OTP, Passkey, OAuth)
All customizations use the CreateSubOrgParams type.

​
Configure defaults for all auth methods

Set defaults in TurnkeyConfig.auth.createSuborgParams, applying the same parameters across methods.
DemoWalletApp.swift
import SwiftUI
import TurnkeySwift
import TurnkeyTypes

@main
struct DemoWalletApp: App {
    @StateObject private var turnkey: TurnkeyContext

    init() {
        // One example wallet config (Ethereum)
        let ethAccount = v1WalletAccountParams(
            addressFormat: .address_format_ethereum,
            curve: .curve_secp256k1,
            path: "m/44'/60'/0'/0/0",
            pathFormat: .path_format_bip32
        )

        var suborgParams = CreateSubOrgParams()
        suborgParams.userName = "User-\(Int(Date().timeIntervalSince1970))"
        suborgParams.customWallet = v1WalletParams(
            accounts: [ethAccount],
            walletName: "Wallet-\(Int(Date().timeIntervalSince1970))"
        )

        let config = TurnkeyConfig(
            // ... your base config (apiUrl, authProxyUrl, rpId, organizationId, etc.)
            auth: .init(
                createSuborgParams: .init(
                    emailOtpAuth: suborgParams,
                    smsOtpAuth: suborgParams,
                    passkeyAuth: suborgParams,
                    oauth: suborgParams
                )
            )
        )
        TurnkeyContext.configure(config)
        _turnkey = StateObject(wrappedValue: TurnkeyContext.shared)
    }

    var body: some Scene {
        WindowGroup { /* ... */ }
    }
}

​
Customize per authentication method

Provide different parameters for each auth method in TurnkeyConfig.auth.createSuborgParams.
DemoWalletApp.swift
import TurnkeySwift
import TurnkeyTypes

// Example: Ethereum account for email OTP users
let emailAccount = v1WalletAccountParams(
    addressFormat: .address_format_ethereum,
    curve: .curve_secp256k1,
    path: "m/44'/60'/0'/0/0",
    pathFormat: .path_format_bip32
)

// Example: Solana account for passkey users
let solanaAccount = v1WalletAccountParams(
    addressFormat: .address_format_solana,
    curve: .curve_ed25519,
    path: "m/44'/501'/0'/0'",
    pathFormat: .path_format_bip32
)

var emailParams = CreateSubOrgParams()
emailParams.userName = "Email User"
emailParams.customWallet = v1WalletParams(
    accounts: [emailAccount],
    walletName: "Email Wallet"
)

var passkeyParams = CreateSubOrgParams()
passkeyParams.userName = "Passkey User"
passkeyParams.customWallet = v1WalletParams(
    accounts: [solanaAccount],
    walletName: "Passkey Wallet"
)

let config = TurnkeyConfig(
    auth: .init(
        createSuborgParams: .init(
            emailOtpAuth: emailParams,
            passkeyAuth: passkeyParams
            // You can also set smsOtpAuth, oauth, walletAuth as needed
        )
    )
)
TurnkeyContext.configure(config)

​
Customize at the function call

You can override defaults at runtime by passing createSubOrgParams into signup helpers.
This takes precedence over config-level defaults.

​
Email or SMS OTP

Use completeOtp(...) or signUpWithOtp(...) with createSubOrgParams.
OtpFlow.swift
import TurnkeySwift
import TurnkeyTypes

var params = CreateSubOrgParams()
params.userName = "OTP User"
params.customWallet = v1WalletParams(
    accounts: [
        v1WalletAccountParams(
            addressFormat: .address_format_ethereum,
            curve: .curve_secp256k1,
            path: "m/44'/60'/0'/0/0",
            pathFormat: .path_format_bip32
        )
    ],
    walletName: "OTP Wallet"
)

// After verifying code (otpId/otpCode), complete the flow with custom params:
let result = try await turnkey.completeOtp(
    otpId: "<otp_id>",
    otpCode: "<otp_code>",
    contact: "<email_or_phone>",
    otpType: .email, // or .sms
    createSubOrgParams: params
)

​
Passkeys

Use signUpWithPasskey(...) with createSubOrgParams.
PasskeySignup.swift
import AuthenticationServices
import TurnkeySwift
import TurnkeyTypes

var params = CreateSubOrgParams()
params.userName = "Passkey User"
params.customWallet = v1WalletParams(
    accounts: [
        v1WalletAccountParams(
            addressFormat: .address_format_solana,
            curve: .curve_ed25519,
            path: "m/44'/501'/0'/0'",
            pathFormat: .path_format_bip32
        )
    ],
    walletName: "Passkey Wallet"
)

try await turnkey.signUpWithPasskey(
    anchor: anchor,
    createSubOrgParams: params
)
