Next.js for Drupal
This is an example on how to implement authentication in Next.js for Drupal.
There are two OAuth 2.0 grants implemented: the Password Grant and the Authorization Code Grant.
The Password grant allows users to login with their credentials i.e a username and a password.
Authorization Code Grant
The Authorization Code Grant redirects the user to the authorization server, in this case Drupal, for authentication.
The user will then be asked to login to the authorization server and approve the client.
Login to your Account
You can use username: member and password: member to login.
