Personal access token
Under the personal access token settings you have the ability to create or revoke a personal access token. A personal access token gives you read-only permissions to everything you have access to.
After having created a token, make sure to copy your token as it will not be visible again. Have a look at the various fields you can copy, including the authorization header for HTTP requests, and the URL with the appended token in order to easily share a link. Once you have created a token, you can also revoke it from this page.
