Cognito for User Authentication
Cognito is Amazon's proposal among its services to organizations to reduce the investment of time and effort in the development of the authentication platform for your applications.
It is very common for activities planned to develop a new application, whether web or mobile, to find the configuration of databases, servers, and a set of tasks largely associated with the authentication process of users using your application.
This process must be carried out very carefully as it is necessary to ensure that security of the personal data of its users and at the same time have one of the robust platform that can scale quickly and securely as it grows the number of users using your app.
It is at this point that Cognito can be of great help by presenting mainly as a tool with features focused on the process of authenticating users to large scale and even to synchronisation your data. These characteristics are the Groups of Users and Identity Groups.
User Groups are directories on Amazon that allow users to obtain the registration and sign-in service to your application and include security levels such as multi-factor authentication (MFA), credential verification, mail verification electronics and telephone. It is also possible to log in through third parties through a identity provider (IdP) such as Facebook, Google,Login with Amazon and home Apple or through SAML and OIDC identity providers.
Identity Groups allow users to obtain temporary credentials to Access Amazon services such as S3 and DynamoDB, they need to be integrated with groups of users to save profile information. Users can authenticate with Cognito User Groups, Facebook, Google and Login with Amazon,in addition, providers such as OIDC and SAML.
Other highlights of Cognito are the large number of users who can reaching numbers of millions of users, with costs varying by the amount active users per month (MAU). In addition, the configurations that must be made to setting user authentication in your app are quite simple even without writing a single line of code.
In conclusion, Cognito is a small and large-scale user authentication service with fairly robust and easy-to-configure features, the main goal of which is to have its developers focus primarily on developing without worrying about authentication issues and all the effort associated with such activities.
