Devices and linking

Using one subscription on more than one device, pairing a device with no keyboard, and why a link can't be undone.

Every device — a phone, a router, an Apple TV — gets its own permanent key the moment you first open the app or start the container, before you do anything else. That key is what "a device" means here; attaching an account number to it is what lets more than one device share a subscription.

Attaching a second device

  1. On the device that already has your subscription, open Account → Create if you haven't already, and note the number down.
  2. On the second device, open Account → Sign in and type the same number in.

Both devices now see the same subscription. There's no limit on which platform either one is, as long as it's a device ForestVPN actually ships on.

Pairing a device with no keyboard

Apple TV and a router have no practical way to type a 32-character number. Instead:

  1. On the device with no keyboard, choose Pair. It shows a short code.
  2. On a phone or tablet that already has your account number entered, type that code in.

This reads the same as signing in, just started from the other end — the code is a one-time stand-in for the number, used once, to make the same permanent link.

This is permanent

There is no unlink. Once a device is attached to an account, that link stays for the life of the device — not a setting, not something support can flip as routine work. If a device is lost, or you're not sure who has the account number any more, write to us: severing a link is possible as an audited exception, and it takes about 24 hours, because it's deliberately not instant.

There's no device list in the app to manage, either. Showing one you could look at but not act on would be worse than not showing it at all, so we don't.

What a linked device can do

A linked device shares the subscription's tier — the same paid plan, or the same free tier. It can't see the other devices on the account, remove them, or tell how many there are. If that matters to you — a shared or borrowed device, say — treat the account number with the same care you'd give a password you can never change: see the account number for what happens if it's lost or shared with the wrong person.
