An authentication service is a mechanism, analogous to the use of passwords on time-sharing systems, for the secure authentication of the identity of network clients by servers and vice versa, without presuming the operating system integrity.

The function of the Authentication Service is to request information from an authenticating party and validate it against the configured identity repository using the specified authentication module.


Amazon Cognito

Amazon Cognito is an Amazon Web Services product that controls user authentication and access for mobile applications on internet-connected devices. The service saves and synchronizes end-user data, which enables an application developer to focus on writing code instead of building and managing the back-end infrastructure. This can accelerate the mobile application development process.

Access control via authentication and authorization requires confirming two things: the identity of the person trying to access the device or website, and if they are allowed to do so. Both aspects are critical in ensuring that organizations can keep their networks and protected resources secure from bad actors. Here is where Amazon Cognito comes in.

Firebase Authentication

Firebase Authentication provides backend services, easy-to-use SDKs, and ready-made UI libraries to authenticate users to your app. It supports authentication using passwords, phone numbers, popular federated identity providers like Google, Facebook and Twitter, and more.

Firebase Authentication aims to make building secure authentication systems easy while improving the sign-in and onboarding experience for end-users. It provides an end-to-end identity solution, supporting email and password accounts, phone auth, and Google, Twitter, Facebook, and GitHub login, and more.

AI/ML Authentication

Using artificial intelligence (AI), advanced authentication is evolving to monitor in real-time and to identify anomalies in the user’s authentication patterns or even threats in the authentication path (such as compromised networks).
