# Understanding your access key

> What the access key is, where to find it, and how to use it in your form.

Source: https://docs.formclick.io/help/access-key-guide

Every form has its own access key, a long ID such as `21e56b6c-55b5-4c8d-ab3b-83222682465f`. It is the only thing that links your HTML to your Formclick form.

## Where to find it

Open the form in your dashboard and go to the **Connect** tab. The key is shown at the top, and every code sample on that page already includes it.

## How to use it

```html
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY">
```

Add it as a hidden field inside the form. For JavaScript and API calls, send it as `access_key` in the JSON body. See [Access key](https://docs.formclick.io/html-forms/access-key) for every option.

## Common questions

### Can I use the same key on several pages?

Yes. Every page using the key sends to the same form. Formclick records which page each submission came from.

### Do I need a new key for each website?

Only if you want separate inboxes, notifications or integrations. Otherwise one form is fine.

### Is it safe to publish?

Yes. See [Is my access key safe in public HTML?](https://docs.formclick.io/help/access-key-security)
