# Pairing the Gate with browsers

![The Mnemonica Gate icon](https://support.mnemonica.com/images/support/gate/paring-the-gate-with-browsers/8f44ec2569ffaac3.png)

After you [install](https://support.mnemonica.com/docs/gate/install-mnemonica-gate) [Mnemonica Gate](https://support.mnemonica.com/docs/gate/about-mnemonica-gate), pair it with your browser. When the Gate is paired, it does all the file transfers.

To pair, copy a 6-digit code from the web app into the Gate. The code is valid for 2 minutes. Use the same account in the browser and in the Gate. You need a [strong session](https://support.mnemonica.com/docs/account/basic-and-strong-sessions) in the browser.

## Pair a new Gate

A new Gate opens on the **Authorize this Gate** screen. The status under the Gate name is **Not Connected**.

### Get a code in the web app

Sign in to Mnemonica in your browser. Click the **Gate icon** in the top bar and choose **Pair Gate...**. The **Pair your Gate** dialog shows a 6-digit code. Click the copy button beside the code.

### Type the code in the Gate

Open the Gate. Click its icon in the menu bar (Mac) or in the system tray (Windows). Click the paste button beside the **Pairing code** field. You can also type the code in the field.

### Authorize the Gate

Click **Authorize**. The web app shows the message **Gate connected**, and the Gate icon in the top bar turns green.

> **Note**
>
> If the Gate icon stays red after the Gate accepts the code, reload the web page.

If the pairing does not work, the Gate shows one of these messages:

| You see                                                   | What to do                                                                                                    |
| --------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------- |
| Code not recognized                                       | Check the code in the web app and try again. If the code expired, click **New code**.                         |
| Too many attempts. Try again in N s.                      | Wait for the countdown to end.                                                                                |
| Could not reach the server                                | Check your connection and your [proxy settings](https://support.mnemonica.com/docs/gate/use-the-gate-with-a-proxy-server). Then try again. |

| The API key used by this Gate has been deleted or revoked | Pair the Gate again from the web app.                                                                         |

## Pair another browser

You can pair many browsers with the same Gate.

### Get a code in the other browser

Sign in to Mnemonica in that browser. Click the **Gate icon** in the top bar and choose **Pair Gate...**. Click the copy button beside the code.

### Type the code in the Gate

In the Gate, click the options button (**⋮**) and choose **Preferences**. Open the **Pairing** tab. Under **Pair another browser**, click the paste button beside the **Pairing code** field. You can also type the code in the field. Click **Pair**.

![The Pairing tab of the Gate Preferences with the authorized account and the Pair another browser field](https://support.mnemonica.com/images/support/gate/paring-the-gate-with-browsers/gate-preferences-pairing@2x.webp)

The **Pairing** tab also shows the account of the Gate and the message **Paired with your browser**.

## Check the pairing status

Look at the color of the Gate icon in the top bar of the web app:

* **Green:** the Gate is paired and connected.
* **Orange:** the Gate is not paired.
* **Red:** the Gate is not connected.

The Gate also shows its status under its name. A green dot and the account email mean that the Gate is connected. A red dot and **Not Connected** mean that the Gate is not authorized or cannot connect.

## If the Gate cannot connect

The web app can show the message **Your Gate can't connect any more**. This means that the Gate has no valid authorization. One of these events caused it:

* An update of Mnemonica retired the sign-in of the Gate.
* Someone deleted the API key of the Gate.
* Someone deauthorized the Gate.

![The Your Gate can't connect any more dialog with the two steps to fix it and the Pair Gate... button](https://support.mnemonica.com/images/support/gate/paring-the-gate-with-browsers/web-gate-cant-connect@2x.webp)

### Update the Gate

Open the Gate and let it update. If it does not offer an update, open the **Preferences** and click **Check for updates** in the **General** tab.

### Pair the Gate again

In the web app, click the **Gate icon** and choose **Pair Gate...**. Type the new code in the Gate.

Until the Gate connects, it shows **Connecting...** and a **Restart** button. If the Gate icon is red, also check these points:

* Your internet connection works.
* The account in the browser and the account in the Gate are the same.
* You did not use **Reset sign-in methods** in *Preferences / Security*. This action deletes the key of the Gate. To pair the Gate again, wait 24 hours and add a strong method. Then pair it from your strong session. See [Lost device and reset](https://support.mnemonica.com/docs/account/lost-device-reset).

If you used **Sign out everywhere**, the Gate reconnects by itself. You do not need to pair it again.

If the problem stays, read [how to reset or remove the Gate](https://support.mnemonica.com/docs/gate/troubleshooting-how-to-reset-remove-mnemonica-gate).

## Deauthorize a Gate

To stop a Gate from working as your account, click the options button (**⋮**) of the Gate and choose **Deauthorize this Gate**. You can also click **Deauthorize this Gate** in the **Pairing** tab of the Preferences. The Gate forgets its API key. The key itself keeps working elsewhere.

To revoke the key everywhere, open *Preferences / Security* in the web app and select the **API keys and devices** tab. Click the options button (**⋮**) on its row. Choose **Revoke**. You need a strong session to do this. Each paired Gate has its own key. The key shows the user and computer name of the Gate, and the kind **Gate**. Read more about [API keys](https://support.mnemonica.com/docs/account/api-keys).
