 For the request to be *secure*, the user in the browser cannot modify the request or make their own valid request to the *token request service* in a way that requests a token for any other user.
 
-The `autoLogin: true` property in the `init()` function causes the Visual Embed SDK to request a new token before the token or the session expires, so that a user never sees the ThoughtSpot embed component in a signed-out state.

 == Define token request service
 There are two options in the `init()` function to define the request to the *token request service*: `authEndpoint` or `getAuthToken`.

 === Multiple user sessions in one browser
-Cookieless authentication is also useful for scenarios where the embedding application allows for being logged into multiple user accounts in different tabs, or quick switches between users. Cookie-based authentication restricts the whole browser to a single logged-in user per ThoughtSpot instance, while cookie-less allows each tab to use a different token without conflicts.

 == Code examples
 The only difference between cookie-based trusted authentication and cookieless authentication in the `init()` function is the value used for the `authType` property.
