```
 
 // Example
 App app = new App("app-id")
 User user = app.login(Credentials.anonymous());
 user.linkCredentials(Credentials.emailPassword("email", "password"));
 
 
```
    Note: It is not possible to link two existing users of MongoDB Realm. The provided credentials must not have been used by another user.
    Parameters:
    
    credentials - the credentials to link with the current user.
    
    Returns:
    
    the User the credentials were linked to.

    credentials - the credentials to link with the current user.
    
    callback - callback when user identities has been linked or it failed. The callback will always happen on the same thread as this method is called on.

  - logOut
```
public void logOut()
            throws AppException
```
    Log the user out of the Realm App. This will unregister them on the device, stop any synchronization to and from the users' Realms, and those Realms will be deleted next time the app restarts. Therefor logging out should not be done until all changes to Realms have been uploaded to the server.
    Once the Realm App has confirmed the logout any registered AuthenticationListener will be notified and user credentials will be deleted from this device.
    Logging out anonymous users will remove them immediately instead of marking them as User.State.LOGGED_OUT. All other users will be marked as User.State.LOGGED_OUT and will still be returned by App.allUsers(). They can be removed completely by calling App#removeUser(User ()}.
