In liwe3, authentication is achieved by using the Next-Auth Package and the JWT package. You can work using the various authentication methods provided by Next-Auth, mainly the Credentials provider (which is the most flexible since you can use any authentication method you want) and the OAuth provider, to login using third party services, such as Google, Facebook, Twitter, etc.

The Credentials Provider

The credentials provider is quite simple, since it calls the nodejs liwe3 backend, with these keys:

  • email - the email of the user logging in
  • password - the password of the user logging in
  • recaptcha - the recaptcha response (by hCaptcha)

To use the Credentials provider, you just need to use the provided Login component that will call the liwe3 backend. If you wish to use a different GUI layout, no problems, just have a look at the Login component source code (which is quite simple) and you should be able to create your own.

The OAuth Provider

For any OAuth provider, you need follow the steps described in the Next-Auth documentation

When you allow users to login using an OAuth provider, you need to create a new user in the backend if the user is logging in for the first time. This is achieved by the NextJS code by performing a remote call to the liwe3 backend. So, please, remember to configure correctly the REMOTE_CHALLENGE in the .env file.

NOTE: REMOTE_CHALLENGE needs to have the same value on both .env file and the data.json/security/remote key in the liwe3 backend. If this value is mismatched, the user will not be able to login.
