# Android SDK setup
> Install and initialize the OwnID Android SDK, choose Core or Compose, and prepare your app for native passkeys.
Use the OwnID Android SDK to add passkey-first authentication and passkey enrollment to a native Android app. Your app remains responsible for user records, sessions, and identity-provider integration.
## Requirements
* Android API 23+
* Compile SDK 35+
* Core Kotlin compatibility baseline: 1.8.22
* Compose UI Kotlin compatibility baseline: 1.9.25
* Jetpack Compose 1.7.8+ for Compose UI
The SDK supports Android API 23 and later, but Credential Manager passkeys require Android 9 (API 28) or later.
## Choose an SDK artifact
| Artifact | Use it for |
| ------------------------------- | ---------------------------------------------------------------------------------------------- |
| `com.ownid.android-sdk:core` | SDK configuration, Elite flow, Headless, Passkey Enrollment, WebBridge, and passkey operations |
| `com.ownid.android-sdk:compose` | Boost flow widgets and SDK-provided Compose UI; includes Core transitively |
```kotlin theme={null}
dependencies {
implementation("com.ownid.android-sdk:core:")
}
```
```kotlin theme={null}
dependencies {
implementation("com.ownid.android-sdk:compose:")
}
```
The Compose artifact already includes Core. Add Core separately only if you need to pin its version.
## Initialize OwnID
Copy the application ID from the OwnID Console and initialize the SDK once during app startup.
```kotlin theme={null}
import android.app.Application
import com.ownid.sdk.OwnId
class App : Application() {
override fun onCreate() {
super.onCreate()
OwnId.initialize {
applicationContext = this@App.applicationContext
appId = ""
}
}
}
```
Besides the Android application context, `appId` is the only required OwnID setting. For optional settings and alternative initialization methods, see the [full configuration guide](https://github.com/OwnID/ownid-android-sdk/blob/master/docs/setup/configuration.md).
## Enable passkeys
Configure Credential Manager and associate your Android app with the relying party domain before starting a passkey flow.
## Choose an integration
Add OwnID widgets to an existing native login or registration screen.
Run the OwnID-hosted authentication experience in an SDK-managed WebView.
Add a passkey for a user who is already signed in.
## Continue with the Android guides
Explore configuration, providers, flows, customization, examples, and troubleshooting.
Update an existing Android SDK version 3 integration.
