Check for a session at startup

When the app is closed and reopened, you need to check for the existence of an access token to see if the user has an existing session.

• Android
• iOS
• React Native

Call the isAuthenticated function if you want to check whether the user is signed in:

const result = await isAuthenticated();
if (result.authenticated !== this.state.authenticated) {
    this.setState({authenticated: result.authenticated});
}

Implementation in iOS and Android native modules checks if the client has an access or ID token. Then the user is considered authenticated and this call returns true. This does not check the validity of the access token which could be expired or revoked. See Keep the User Signed In to understand how to get a fresh access token.
