Heroku easily integrates with Auth0 to enable single sign-on (SSO) to Heroku using the same credentials and login experience as your other SSO-enabled service providers.
Using SSO, an employee logs in to Heroku using your identity provider’s interface instead of the Heroku login page. The employee’s browser is then redirected to Heroku, authenticated and ready to go. When SSO is enabled, Heroku’s own login mechanism is disabled, meaning that authentication security is shifted to Auth0 and coordinated with your other service providers.
