Navigate between organizations without logging out or prompting for relogin

Hello,

My use case is as below.

  1. My application has multiple projects which enduser can be part of.
  2. A user can have different role in different projects.

As I understand, to achieve this, we need to use auth0 organizations as it provides a way to bind the roles to particular org rather than directly to user. Please suggest if there is another way to achieve this.

But to use organizations, it would require user to provide the orgName, username and password at the time of login itself. But in my application, this is not the case. Is there a way where user can first login(not to any org) and then be able to navigate to different organizations without giving the credentials again and without logging out.

Thanks in advance!
