Authentication is an important concept, a function that all web applications today need to implement to protect the information of applications and users.

In this new book “Angular Authentication using OAuth2 and OpenID Connect – Second Edition”, I will guide you in detail on how to implement authentication for Angular applications using OAuth2 and OpenID Connect.
