Hello, I just started using your service, so far so good. But I have one little concern with respect to security. The application is not logging out after some time. it always says connected even if I restart my computer. seems like the session is based on cookies or something?. But apart from above, I feel insecure with security because your service does not have two-factor authentication. because If someone has/hacks my password of your service then, they can able to spin as many droplets they want and make me pay for it since I connect DigitalOcean from your service. Is there any plan for implementing two-factor security like SMS/email of thru authentication app? SSL RSA Key token?
