To create custom authentication in CakePHP, you can follow these steps:

Step 1: Create a new Authentication Service Create a new authentication service that extends AuthenticationService and implements the AuthenticationServiceInterface. This service will be responsible for authenticating users and storing their authentication data.

Step 2: Create a new Authentication Adapter Create a new authentication adapter that extends BaseAuthenticator and implements the AuthenticatorInterface. This adapter will be responsible for authenticating users based on their credentials.

Step 3: Configure the Authentication Middleware Configure the authentication middleware to use the new authentication service and adapter. This middleware will be responsible for intercepting requests and checking if the user is authenticated.

Step 4: Implement the Login Action Implement the login action in your controller to handle user authentication. This action should receive the user's credentials and pass them to the authentication service for verification.

Step 5: Implement the Logout Action Implement the logout action in your controller to clear the user's authentication data and redirect them to the login page.

Step 6: Update the User Model Update the user model to include the authentication data. This data should be stored in the user's session or in a cookie, depending on your application's requirements.

Once you have completed these steps, you should have a custom authentication system in CakePHP that can be used to authenticate users based on your application's specific requirements.
