Failed silent Authentication - Login Required


I am developing single page application in reactjs. We are registering user with username/password given by Auth0 login page. But when we make silent token authentication it throws “Login Required”. I am not sure where i am missing. When i look the logs i get below error log. But this works for old application deployed an year ago.

My code for renewal:
webAuth.checkSession({}, (err, authResult) => {
if (err) {
return false;
if (!authResult || !authResult.idToken) {
console.log(“No response during renewal”);
return false;

Hi @sushanthchandrasekar,

Welcome to the Community!

This error can happen when the auth0 cookies are not be sent correctly or are being blocked by ITP, or some sort of extension. Have you tried an incognito window? Or any other browsers?

Hi Dan,

Thanks for the reply.

"A cookie associated with a cross-site resource at was set without the SameSite attribute. A future release of Chrome will only deliver cookies with cross-site requests if they are set with SameSite=None and Secure. You can review cookies in developer tools under Application>Storage>Cookies and see more details at and" in chrome incognito

We have found the issue due to sameSite cookie value in incognito window. However, as of now it is working in normal window but not in private or incognito window. Below is error thrown during renewal call:

code: “login_required”
description: “Login required”
error: “login_required”
error_description: “Login required”

Is there any way to handle such cookies in incognito window too?

Hi @sushanthchandrasekar,
