AWS Single Sign-On vs. Auth0

AWS Single Sign-On (SSO) is a cloud SSO service that makes it easy to centrally manage SSO access to multiple AWS accounts and business applications. It enables users to sign in to a user portal with their existing corporate credentials and access all of their assigned accounts and applications from one place.

Safeguarding billions of login transactions each month, Auth0 delivers convenience, privacy, and security so customers can focus on innovation. Auth0 is part of Okta, The World’s Identity Company™.
