# Authentication

In this section of the documentation, you will find information about how to create and manage your tokens and how to use your token to authenticate.

The Sesame Data uses Basic Authentication, utilising a combination of a username and API tokens as passwords. Upon token generation, clients will receive their unique password. This password and their client-specific username are required as authentication when making requests. 

<table data-header-hidden><thead><tr><th width="131"></th><th></th></tr></thead><tbody><tr><td>Username</td><td>A unique code belonging to each client. This will be available in the Sesame Data Experience</td></tr><tr><td>Password</td><td>The token which allows you to make requests. This is generated in the Sesame Data Experience</td></tr></tbody></table>

Additionally, the API provides support for IP whitelisting, enhancing data security by restricting authentication to a predefined list of IPs. This feature ensures that only authorised IPs can authenticate by presenting a valid token.
