# Chrome Extension Guide

> Keep LinkedIn senders connected automatically by syncing the session cookie from the owner's own browser.

LinkedIn ends sessions from time to time. Without the extension, the account owner has to log in again each time. With it, the platform reconnects on its own, using the session cookie from the owner's browser.

## What it does

* It runs in the **account owner's own Chrome**.
* It syncs the LinkedIn session cookies and browser details **every 3 hours**, and immediately whenever LinkedIn changes the cookie.
* Cookies are encrypted when stored.
* It **never sees the owner's password**.
* Its pairing token only allows uploads for **one sender**.
* It refuses to sync if a different LinkedIn account is logged in.

It applies to LinkedIn senders only. Mailboxes stay connected through OAuth.

## Set it up

<Steps>
  <Step title="Issue a pairing token">
    A Manager opens the sender's **Extension** tab and clicks **Generate pairing token**.

    <Warning>
      The token is shown **once**. Copy it straight away and send it to the account owner over a private channel.
    </Warning>
  </Step>

  <Step title="Install the extension">
    The account owner opens `chrome://extensions`, turns on **Developer mode**, clicks **Load unpacked**, and selects the extension folder they were given.
  </Step>

  <Step title="Pair it">
    They paste the token into the extension and press **Pair**.
  </Step>

  <Step title="Stay logged in">
    They stay logged in to LinkedIn with the same account and leave Chrome running.
  </Step>
</Steps>

<Note>
  Pairing tokens can only be issued while **Cookie-mode opt-in** is on under [Settings → Workspace](/getting-started/platform-overview/workspace-settings). It's on by default.
</Note>

## Revoke access

* **Regenerate pairing token** stops the old token from working immediately. Cookies already stored are kept.
* To remove everything, [disable the sender](/senders/sender-profiles#danger) with **Purge stored secrets** ticked.
