Téma: How to Implement User Log-in with PayPal
Curiosity is one of the most important traits in our job. The other day, I found myself exploring PayPal documentation to find something interesting to learn (and share). After a while I stumbled upon the Log In with PayPal tool.
With the “paypal login” tool, your users can authenticate into your application using PayPal. It’s the same procedure we already know for Facebook, or maybe Twitter and GitHub.
Using this type of authentication is recommended if you want to integrate it with an e-commerce website, but you can use it in every situation and application that requires a user account or membership.
Why use ‘Log In with PayPal’?
One of the most important reasons to use it is simplicity. Your user will not need to remember another set of credentials – the same advantage OAuth via FB, Twitter, etc have. Also, the login procedure is absolutely secured: fewer concerns for you. However, it’s not just an email and a password.
When you create a PayPal account there is a lot of information that you specify. This info, using the APIs, can also be used in your application in many useful ways. One of the best examples I can give is the e-commerce one: why bother your user with asking him for a shipping address if you already know it? He already told PayPal where he lives! In terms of user experience, a simple button is way better than filling a form with many fields… and when it comes to shipping there are at least three or four of them.
