That's it. Your app is ready. Now head over to your mCloud portal.
In your mCloud portal, click on your name, and then select Edit details:
Now scroll down until you see Two factor auth (Authy), check Yes box and save changes:
After this, you should automatically get a HostBill profile in your app. Next time you want to login to your mCloud portal, you will be asked how you want to receive the Authy token.
Click on "Request token via SMS" so the space for the token appears and you'll get a notification on your phone to check your Authy token.
That's it. Your 2FA is now active.
