Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.landytech.com/sesame-data-v2/authentication.md). # Authentication 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.
UsernameA unique code belonging to each client. This will be available in the Sesame Data Experience
PasswordThe token which allows you to make requests. This is generated in the Sesame Data Experience
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. You may also find it valuable to explore our tutorial on [Using Sesame Data with Postman](/sesame-data-v2/tutorials-recipes/using-sesame-data-with-postman.md).

--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.landytech.com/sesame-data-v2/authentication.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
