I’ve studied Oauth 2.0 many times.

As far as I remember, When I was a new employee, when I prepared the IDP project early last year, etc.

I’ve developed biometric authentication stuff, authentication apps for ios, android as a security app developer.

Since almost that time, I dealt with the client-side, I’ve never deep dived this tech.

So there are unclear parts in Oauth2.0 for me.

Anyway, This book has good content regarding Oauth 2.0.

It is quite deep in content, it was very helpful for understanding because it informed a lot of implementation intentions.

So I’m very pleased to meet this book.

It may give me a lot of improvement my skill.

Unfortunately, a lot of typos in Korean have been found.

This was the weakest point of this book.
