Let user login into my SPA (Reactjs) based on IdToken using Okta-React SDK


Hope you are doing good.

I’m struggling with the user authentication based on IdToken. What I’m trying to do is. If I go to my Okta-Dashboard and click on my application. Okta Redirect me with the IdToken. With that IdToken I’m trying to login-user into my Reactjs SPA.

I should not display the log-in page to the user, instead, I have to validate the ID token received from Okta for authenticity and establish Okta SSO session. I’m already using Okta-React SDK.

I have gone through the number of posts and official docs but unable to find help may be due to my lack of Okta-Domain knowledge.
I’m really stuck in it. Please guide how can we validate the ID token received from Okta-Dashboard => My Apps Section and use the same token for validating the user instead of asking the user to log-in again.

Looking forward to you.


Hi there. First you want to make sure you have you app setup for IDP initiated flow with the following settings:

The Initiate Login URI is where the user will be taken when they click the application tile. In your code at this endpoint, you will want to do a session check to see if the user has an Okta session. Then, you will want to initiate the OIDC flow to retrieve tokens if that session exists. Here’s an example:

const oktaAuthClient = widget.authClient;
  .then((exists) => {
      responseType: ['token', 'id_token'],
      .then((res) => {

//if no session, render sign-in widget

  el: widgetRef.current,
}).then((tokens) => {
}).catch((err) => {
  throw err;

Hopefully you can apply this to your particular use case/codebase.
