Questions

Does it work when my computer sleeps?

No. Your computer must stay on. When it sleeps, the door disappears.

Where does my code go?

Nowhere. Your phone talks to your computer directly over your private network.

Can I use it outside the office?

Yes, over your company VPN or your own private tunnel. Your work computer just needs to stay on.

Do I need an app?

No. Your phone's browser is enough. iOS and Android apps are optional.

Urgent issue? Your agent is one tap away.
