# Authentication

The Mem API uses API keys for authentication. To obtain an key, visit the API section in your Mem settings.

Remember that your API key is a secret! Do not share it with others or expose it in any client-side code (browsers, apps). API keys should be securely loaded from an environment variable or key management service on the server.

API keys should be provided via [HTTP Bearer authentication](https://swagger.io/docs/specification/v3_0/authentication/bearer-authentication).

```text theme={null}
Authorization: Bearer $MEM_API_KEY
```
