# Authentication

> Authenticate with MyVocal APIs using the accessKey header.

## How authentication works

MyVocal API uses a single header for authentication on every endpoint:

```http theme={null}
accessKey: <your_api_key>
```

## Where to get your API key

1. Sign in to [MyVocal Account](https://www.myvocal.ai/account).
2. Open Account Info.
3. Copy your API key.

## Header format

<ParamField header="accessKey" type="string" required>
  API key used to authenticate your request.
</ParamField>

## Security best practices

* Keep API keys on your backend server.
* Do not expose API keys in frontend code or mobile apps.
* Do not commit API keys to Git repositories.
* Rotate key immediately if you suspect leakage.

## Example request

```bash theme={null}
curl --location 'https://api.myvocal.ai/sound_clone/api/v1/user/info' \
--header 'accessKey: <your_api_key>'
```
