imageWhen I had been implementing a project on Yii framework, I got the task to make the registration and authorization of users through the different services (Google, Facebook, Twitter, etc).

This task has two ways of solution:
• Using an authorization service, such as Loginza;
• Implementing an authorization of functions independently for each service.

Here are benefits to use the authorization service:
1. Simplicity and speed of installation;
2. There is no need to learn the details of authorization through each provider.

However, a self-authorization has other advantages:
1. Full control over the process of authorization: what we will write in the authorization window of provider, what information we will receive and so on;
2. Ability to change appearance of the authorization widget in compliance with a design of the website;
3. Ability to invoke methods of API when we authorize over OAuth, if the service provider provides them;
4. There is less dependency from the different services and it is more reliable.

I chose the second option, because I did not have the ready extensions for yii, and I was wondering how such authorization system looks like from the inside. It was part of a module to manage the users at first, but later this functional has been extracted in a separate extension, which can be used easily in any project.
