J.A.R.V.I.S.
Private assistant. Only your own devices get in.
Set up this device. Jarvis will save a passkey here (Face ID, Touch ID or your phone), so next time you just sign in. This link works once.
No devices are set up yet. On your Mac, open Jarvis → Settings → Access from anywhere → Add a device.
Untick “keep me signed in” on shared or school computers.
