# Passwordless Chrome Extension

If you sell on Poshmark, Mercari, or Whatnot and have access to a computer, it's worth familiarizing yourself with Nifty's **Passwordless Chrome Extension**. It’s quick, easy, and guaranteed to work.

{% hint style="info" %}
**Requirements:** The extension only works with Google Chrome on a computer. It isn't available on mobile browsers or other desktop browsers.
{% endhint %}

### How to set it up

1. In Google Chrome on a computer, open our [Chrome extension](https://chromewebstore.google.com/detail/nifty/ggcfdkgmekpddencdddinlmpekbcohoa).
2. Click **Add to Chrome**, then confirm when prompted.
3. From the same browser, log into your marketplace account (Poshmark, Mercari, or Whatnot).
4. Go back to Settings → [**Connections**](https://app.nifty.ai/settings/connections) — you'll see a **Connect** button instead of a password field.

### How it works

The extension uses your existing session with poshmark.com, mercari.com, or whatnot.com and shares it with Nifty so we can connect without you typing your marketplace password into Nifty.

### How it affects your service

It doesn't! The extension is only used for the initial connection — it doesn't change how Nifty works. Nifty still runs entirely in the cloud, and you don't need to keep the extension installed or your computer on after connecting.

### Troubleshooting

**Not seeing the Connect button?** Make sure you're using Google Chrome on a computer and that the extension is installed and enabled — other browsers aren't supported.

**Clicked Connect but got a login page?** This usually means you're not logged into the marketplace on your current browser. Log in and confirm the connection by visiting the marketplace directly (for example, poshmark.com), then try again.

**Connection won't establish or disconnects immediately?** Your session may be stale. Sign out of the marketplace, sign back in, then use the extension again.

**Stuck in a connection loop?** If the connection window opens and immediately closes, the Nifty extension likely doesn't have the necessary permissions to access site data.

1. **Open Extension Settings**: Click the Nifty Extension, and select Manage Extension. If you don't see it, try clicking the **Puzzle Piece icon** in your browser.<br>
2. **Adjust Site Access:** Scroll to the Site Access section.
3. **Enable Permissions:** Toggle the setting to "On" for all websites.\

4. **Retry:** Restart your browser and try connecting again.

### Reconnecting

When you're automatically logged out of a marketplace (a normal security feature), connections made via the extension will expire too. To reconnect, make sure the extension is still installed, log back into the marketplace, and click **Connect** on Nifty.
