Have you ever noticed when logging into Spotify or any other platform that you have the option to login using Facebook or Instagram? This is possible thanks to OAuth 2.0 technology and their authorization server. You see, OAuth 2.0 is an open standard for access delegation which supports easy integrations with various platforms, simplifying the customer experience for everyone.

Let’s dive into how this system is structured. OAuth 2.0 works with interconnected APIs that enable an easy exchange of permits and data through the flow of API keys and tokens that ultimately allow information to be transferred from a platform to a web or mobile application. Think about OAuth 2.0 as a framework rather than an actual protocol. It works by delegating access to a third-party application from the source authentication server by securely issuing and validating tokens for services on the internet.

Its advantages

  • Manage various grant types There are four grant types: authorization code grant, implicit grant, password grant and client credentials grant. All of these are managed through AOuth 2.0 to offer better integration with various APIs.

  • Make communication between platforms easier OAuth involves three main parts in its process: the resource owner, the client application and the authorization server (OAuth) and makes communication between the three of them extremely easy, obtaining the required data in just a couple of seconds.

  • Used by many platforms Many companies and platforms use OAuth for authorization, erasing the need to create an account for the third-party application.

  • Keep your data protected Using an OAuth API authentication solution with API keys and tokens, you can easily exchange the information you require securely.

Some final words

All in all, we can explain OAuth in four simple steps:

  1. App requests authorization from User
  2. User authorizes App and delivers proof
  3. App presents proof of authorization to server to get a Token
  4. Token is restricted to only access what the User authorized for the specific App
