# signInWithOAuth

```ts theme={null}
function signInWithOAuth(providerType: OAuth2ProviderType, options?: {
  idempotencyKey?: string;
}): Promise<void>;
```

Initiates the sign in flow with an OAuth provider (Google, Apple, Telegram, and X are currently supported).
In a web application, this will redirect the user to the OAuth provider's sign in page.
