# Authentication

This API supports three primary authentication methods: **API Key**, **Environment-based** authentication and, optionally, **Fingerprint**-**based** session handling.

### API Keys

Obtained from the dashboard, It requires a unique `apiKeyUUID` and `apiKey`. These credentials must be included in every request, and the `apiKey` should be stored securely, as it is shown only once.

### Environments

Obtained from the dashboard, It requires a unique `environmentUUID` and `envSecret`. These credentials must be included only when creating a session (only if fingerprint was used), and the `envSecret` should be stored securely, as it is shown only once.

### Fingerprints

An optional feature that generates a unique secret for each client user device. This allows session data to be encrypted using both the `envSecret` and the `fingerprintSecret`, enhancing security by ensuring that session data can only be decrypted with both secrets.
