# Authentication

We don't yet have a formal API key authentication mechanism, but have one in the works. For now, you'll have to authenticate in the UI application and copy your JWT in the Firebase localStorage database. Here are the steps to get that value (note that this is in Firefox, so some steps might vary on other browsers):

1. Login to the application.

2. Open the Storage tab and find the `Indexed DB > https://app.holder.xyz > firebaseLocalStorageDb > firebaseLocalStorage` item.

3. Copy the `accessToken` value found under `value > stsTokenManager > accessToken` (screenshot not shown for security reasons).
4. Paste that token under an `Authorization` header in your favorite API tool. It is a `Bearer` token, so the format would be:

```json
{
  "headers": {
    "Authorization": "Bearer your_token_here"
  }
}
```
