Devices & sessions

Each browser or app you sign in with is a separate device with its own keys.

Signing in on a new device

1. Sign in. The new device is unverified.
2. Verify it from a device you already trust (compare emoji), or enter your recovery key.
3. The device can now read your encrypted history and is trusted by your contacts.

Reviewing devices

In the chat app open Settings → Sessions to see every signed-in device, when it was last active, and whether it's verified. Sign out any device you don't recognise. Signing out other devices asks you to confirm with your Lumen account.

Portal sessions

Sessions on this website (portal) are separate. Review them under Security center → Active sessions.

Lost device

Sign out the lost device from another session as soon as possible, and change your password if it might have been unlocked.
