Amazon Cognito is a simple user identity and data synchronization service that helps you securely manage and synchronize app data for your users across their mobile devices. You can create unique identities for your users through a number of public login providers (Amazon, Facebook, and Google) and also support unauthenticated guests.
Amazon Cognito makes it easy to save mobile user data, such as app preferences or game state, in the AWS Cloud without writing any backend code or managing any infrastructure. You can save data locally on users’ devices allowing your applications to work even when the devices are offline. You can also synchronize data across a user’s devices so that their app experience will be consistent regardless of the device they use. With Amazon Cognito, you can focus on creating great app experiences instead of having to worry about building and managing a backend solution to handle user authentication, network state, storage, and sync.
