# signIn

Sign in using the configuration object.

```
Promise<SignInResponseI|SignInErrorI>|void signIn(
	optional ClientConfigI signInConfig
);
```

## Parameters

`signInConfig`

The configuration object used to sign in the user.

## Discussion

By default, the [`signIn`](/documentation/SigninwithAppleJS/AuthI/signIn) method uses the configuration object created during initialization. However, you can override the initialization values by passing in a new configuration object.
