# Authentication

Rocket.Chat provides authentication endpoints that enable users to sign in to a workspace using either a username and password or supported third-party identity providers such as Google and Facebook.

A successful login response returns the following:

- `user-id` : The unique identifier for the authenticated user.
- `authToken` : A temporary authentication token.
- Basic user details: Additional information associated with the user account.

To make authenticated API requests, include these headers with every request:

- `x-user-id` : The authenticated user’s ID.
- `x-auth-token` : The temporary authentication token issued during login.
