# Authentication

## How this example works

OpenLoyalty uses JWT Tokens to authenticate all API calls.

Properly setting up authentication is crucial for maintaining application security and ensuring uninterrupted service. This helps avoid issues such as excessive request rates or the use of invalid or expired tokens.

***

## Try yourself <a href="#to-try-it-yourself" id="to-try-it-yourself"></a>

* Login with the admin username and password\
  Endpoint: `POST /api/admin/login_check`
* Save `token` and `refresh_token` from the responses
* Refresh your previously saved token\
  Endpoint: `POST /api/token/refresh`
* Input the token in the header for all the subsequent requests&#x20;
