# Use OAuth to Authenticate to StreamNative Cloud

StreamNative Cloud supports the [OAuth 2.0](https://oauth.net/2/) protocol for authentication and authorization. OAuth is an open-standard protocol that grants access to supported clients using a temporary access token. Supported clients use delegated authorization to access and use StreamNative Cloud resources and data on the behalf of a user or application.

Summary of key features provided by OAuth 2.0 support in StreamNative Cloud:

* Manage application identities and credentials through Auth0.

* Authenticate with StreamNative Cloud resources using short-lived credentails (JSON Web Tokens).

* StreamNative Cloud's OAuth 2.0 service provides OIDC-based tokens for authentication and authorization that are based on the [OAuth 2.0 Authorization Framework \[RFC 6746\]](https://tools.ietf.org/html/rfc6749) and is compliant with [OpenID Connect (OIDC)](https://openid.net/connect/).

* You can configure OAuth using the StreamNative Cloud Console and StreamNative CLI.

## Limitations

OAuth 2.0 for StreamNative Cloud includes the following limitations:

* StreamNative Cloud only uses StreamNative's Auth0 service as identity provider. It doesn't support using your own identity provider yet.

## Access token format

StreamNative Cloud only accepts JSON Web Token (JWT) access tokens, based on an open, industry standard for representing claims to be transferred securely between two parties. A JWT is a string that represents a set of claims as a JSON object in a JSON Web Signature (JWS) or JSON Web Encryption (JWE) structure, enabling the claims to be signed or encrypted.

Each JWT includes a header, body, and signature that is formatted like this:

```
header.body.signature
```
