Users, licenses and security

Sessions and devices

One web session and one active handheld per user, the session-open-on-another-device screen, sign-out after inactivity and blocking a lost handheld.

All plans

Each license belongs to one person. Chainlink ensures that a user is not used on several devices at the same time, without stopping operations.

Web sessions

  • A user has one open web session (two in Enterprise, if your company configures it).
  • If the user signs in from another device, Chainlink warns: «Your user has a session open on another device». With Continue here, the other session is closed; the other device is notified in less than a minute. With Cancel, nothing is closed.
  • The session closes automatically after 8 hours without activity (your company can set it from 1 to 12 hours) and always 12 hours after it started.
  • Changing your password closes your other sessions.

Handhelds

  • A user uses one handheld at a time. If the user signs in on another one, the session on the previous device ends and the app explains why.
  • The first time someone signs in on a handheld, the device is registered. By default it is approved automatically, up to 2 devices per license. If your company uses manual approval, the app shows «This device is waiting for approval» until an administrator approves it.
  • To change shifts on the same handheld, use Profile › Switch user.

For administrators

In Settings › People and access › Security and access (permission «Manage security»):

  • Active sessions: who is signed in, from which browser and IP, and Sign out for any of them.
  • Devices: approve, block, rename or revoke handhelds. Blocking or revoking ends the device's session immediately.
  • Policies: sessions per user and inactivity.
