Remove or migrate stormpath

I have a simple application (developed back in 2016) that interact with twilio API (send/receive messages). The previous developer use stormpath for authentication. Stormpath was sold for Okta 2017 and the system was down since then. And now I need to bring the application online again. Since the application is for personal purpose ( I only intend to create several account for friends & family to use). I think I dont need to use stormpath any more. I only want a barebone system that work. So Im looking for someone who can help me remove stormpath from my nodejs application.
