How To Implement OAuth User Authentication in Next.js
In this article, we will learn how to add user authentication with OAuth providers in your Next.js app. To do so, we’ll be using NextAuth.js, which is a user authentication solution that simplifies the whole process and has built-in support for many popular sign-in services.
What’s OAuth?
OAuth (Open Authorization) is an open standard for access delegation, commonly used as a way for Internet users to grant websites or applications access to their information on other websites but without giving them the passwords.Â
When you use OAuth authentication with providers (like Google, Facebook, Twitter, etc.), you are using a protocol that allows you to authorize applications to use your personal information from the provider without needing to expose your password. This is achieved by sharing tokens instead of credentials, which can be restricted for use with specific resources or services.
