Imagine you buy a piece of land for yourself. What is the first thing you will arrange for once the paperwork is complete? In India, at least we will put some kind of bordering wall that will help prevent trespassing. Now, for example, I build a house on that plot. I use a lock to protect it and only those with the key will be able to get into the house. Since I fear about the safety of my house, I decide to install a 2-factor authentication there. After unlocking, the person needs to go through a face detection mechanism to get the door unlocked. Thus, only people with verified faces will be able to get through the door. This process of verifying a person's identity is called authentication. Further, I decide that my room will not be accessible to anyone, thus use another lock for it whose key only I possess. Tomorrow, if I lend the key to my room to my mother, she will be able to access it too. Thus, the key possessor gets rights of access. This process of verifying if a person has access is called authorization.

With the shift of work online and an enormous rise in cyber attacks, ensuring cyber security has become the need of the hour. Various methods of authentication and authorization can be used to implement security. These include methods based on sessions, cookies, tokens and also other methods like Multi-Factor Authentication, Passwordless authentication and social media authentication.

Having understood this, let's dig deep into Auth0 and the reasons that make it a platform that you MUST use in your next project!

What is Auth0?

Auth0 is a secure platform that offers both authentication and authorization services. Its flexibility and ease of application make it popular all around the world.

With so many different types of authentication techniques available, selecting the right one for your product may be challenging. Auth0 streamlines this procedure while also allowing you to personalise your sign-in page with a variety of functionalities.

Auth0 helps you in configuring authorization and authentication services for various social networks. It employs token-based authentication, which employs temporary pointers known as tokens. This approach prevents the use of cookies, therefore avoiding data exploitation via cookies. It also enhances your website's or app's performance and scalability.

Please keep in mind that Auth0 and OAuth are not the same thing. Auth0 is a business, whereas OAuth is a protocol.

There are several social networks, including Google, Facebook, and Twitter. And each of these services has its own authentication and authorization scheme.

Where did Auth0 originate from?

Auth0 was founded in 2013 by Eugenio Pace and Matias Woloski. Authentication and authorization services were in high demand at the time, but the complexity made it difficult to incorporate modifications. Auth0 began with the goal of providing individuals and businesses with ease of identity, and the company focused on developing proper documentation and guides to offer users and developers with the information they needed to deploy the services. Auth0 is developer-centric and can handle the majority of authentication and authorization use cases. IN 2015, Auth0's focus moved to scalability, trust, compliance, and enterprise readiness. Auth0's vision to solve all Identity and Access Management requirements remains unchanged. The team is always working to streamline the process and make it more flexible for developers. With all of the investments and support from the developer community, Auth0 is now growing and building its team in order to take the existing platform to the next level.

Where can you use Auth0?

• Customizing the authentication process
• Securing Apps and APIs
• One-Time Passwords (OTP)
• Single Sign-On (SSO)
• Multi-Factor Authentication (MFA)
• Monitoring the users that come to your site

Why should you use Auth0?

1. The variety of Social Networks you can sign in using

Auth0 allows Sign-in using various Social Media Networks. The authentication and authorization process is taken care of by Auth0. This helps you focus on your app entirely.

2. Customizable UI

Auth0 allows you to use both built-in and custom user interfaces. From enhancing customer experience through seamless SSO to making MFA as simple as a button click - your login box must strike the appropriate mix of user ease, privacy, and security. Auth0 is an adaptable identification solution that can be tailored to your specific requirements.

3. Security Considerations

When it comes to authentication services, the security of user data is without a doubt an obstacle. Fortunately, Auth0 has addressed this issue. The OAuth 2.0 authentication protocol provides Auth0 security by allowing the application to give access permissions to the user's resources on another service. The protocol eliminates the need to trust the app's login and password. You can also provide a restricted set of access privileges (rather than a full set) at any time. It also includes an attack protection feature. Customers and their users will be notified of any suspicious behaviour, and extra security measures will be implemented.

4. Analytics

Auth0 provides powerful capabilities for tracking people on a website or in an application. You can build funnels, track user retention, and optimise your sign-up process. Integration Auth0 Analytics enables the capture and measurement of specific events such as the number of new and existing users, the number of users registered in each application, in-app login activity in the previous year, the number of new registrations during the current day, logins and new registrations during the previous week, and identity providers used to log-in to the application. Auth0 Analytics presents this data in the form of easy visual graphs and provides the option to filter reports for more precise information.

5. Detailed Documentation

Auth0 provides detailed documentation and clear code examples in popular programming languages. Since it has a large number of libraries with different technologies, proper documentation is the need of the hour. Being developer-centric is one of Auth0's key points. The documentation is well-defined and contributes to the growth of the developer's knowledge in a variety of areas.

Conclusion

To sum it up, Auth0 provides enhanced security for the user while also providing a handy tool with high-quality features that developers want. Furthermore, the Auth0 administration page is aesthetic, simple, and provides a plethora of options that app administrators will find useful. As a result, such a service with a comprehensive set of contemporary authentication capabilities will meet your expectations and demands. Auth0 offers the most comprehensive capability for ensuring user authentication and authorization, with thorough statistics, a wide range of possible providers, and a diversified collection of developer-friendly tools.
