Login Feature Overview

To write or edit posts on a bulletin board, a login process to verify the user’s identity is essential. Through Vibe Coding, you can easily implement login features while complying with security standards and integrate them with the bulletin board service.

​
Step-by-Step Login Implementation

​
1. Security Settings and Authentication Method Definition

Explain to the AI what method of login you want. We recommend a combination of Spring Security and JWT (JSON Web Token), which is the recent standard.
Prompt: “Add a login feature to our board. I want to use Spring Security and apply the JWT token authentication method for security. Include ID, password, and email in the user information.”

​
2. Authentication Logic Creation (Logic Create)

The AI creates the User entity, the AuthController responsible for authentication, and the SecurityConfig file containing security settings.
  • Using Tools: The AI automatically configures the filters and handlers needed for login through create_new_file.

​
3. Integration with Bulletin Board Logic (Logic Update)

Update the previously created bulletin board logic to restrict permissions so that only logged-in users can write posts.
Prompt: “Update the post creation (post) and modification (update) logic. Now, make it accessible only to users who have a JWT token after logging in, and add validation logic so they can only edit posts they wrote themselves.”

​
Utilization Tip: Social Login Integration

With Vibe Coding, you can solve complex OAuth2 settings just through conversation.
Prompt: “Expand the feature so users can also log in with their Google accounts. If Google login is successful, have them automatically registered as user information in our system.”

💡 Precautions for Login Implementation

  • Password Encryption: When the AI generates logic, make sure to use BCryptPasswordEncoder or similar to ensure passwords are encrypted before being saved.
  • Logout Handling: It’s recommended to choose either a method to expire the token on the client side or a server-side blacklist method and request logout logic as well.
  • Error Messages: Strengthen security by using general messages like “Invalid ID or password” rather than specific errors like “ID does not exist.”
