Core Oneby Yumi

Secure remote access

How it works

A device at your place, your account online, and an encrypted link between the two. Here is what happens, step by step.

Linking a device

It takes about a minute. Nothing to install, nothing to change on your router.

  1. Plug in the device

    Power it on and wait for it to boot: it then shows a link code.

  2. Read the code

    The code appears on the device screen, its local page or the printed ticket.

  3. Type it in

    Enter it below and the device is tied to your account right away.

The code shown by the device lasts a few minutes and works only once: nobody can link your device in your place.

Good to know

What is a Core One?

A small device you plug in at home or at the office. It runs your services locally, and this site is its front door when you are away.

Remote access, no port to open

The device calls our servers, never the other way round: the link leaves your network just like a web page would. No port forwarding on your router, no static IP, nothing exposed to the Internet.

What keeps your devices safe

Traffic is encrypted end to end, every device carries its own revocable token, and you alone see yours. Unlink a device and it loses access that very moment.
