Amazon Cognito

Amazon Cognito is a web service that controls user authentication and access for mobile applications on internet-connected devices. It allows simple and secure user authentication, authorization and user management for web and mobile apps. The service saves and synchronizes end-user data, allowing an application developer to concentrate on writing code rather than constructing and maintaining back-end infrastructure. It helps in spreading the development process of mobile apps. With Cognito, a user or visitor can sign in with a username and password through Amazon, or through a third party app like Facebook, Google or Apple. Thus, with Cognito, a developer can easily add user sign-up, sign-in and access control to their apps with its built-in user interface and easy configuration. Cognito is part of the Amazon Web Services (AWS) ecosystem. The Cognito console itself is part of an organization's AWS where they can see all information about their Cognito account and billing.
