Is there a way to send user info to auth0 to get user access token for SPA application.

I only see a way to send client credentials via post call to get access token but thats not user specific.  
Problem that we are trying to solve:  
User A is part of application X and Y. User logins to application X via /authorize and gets access token as expected.  
Now user wants to navigate to application Y where the user has the same identity i.e. email\_id. We want the user to redirect to application Y without logging in again. Is there a way to send user email id to auth0 and request for access token for app Y and redirect to app Y by setting the received token.

All of our SPA SDKS implement the [authorization code flow + PKCE](https://auth0.com/docs/get-started/authentication-and-authorization-flow/authorization-code-flow-with-proof-key-for-code-exchange-pkce) which is the best practice for authenticating/authorizing users in a SPA.

This describes [SSO](https://auth0.com/docs/authenticate/single-sign-on) which is also supported by Auth0 SPA SDKs by way of [Universal Login](https://auth0.com/docs/authenticate/login/auth0-universal-login).
