“How to Implement Front-end Automatic Login”

To implement front-end automatic login, follow these steps:

  1. Generate a JSON Web Token (JWT): When a user logs in and selects “Remember Me,” create a JWT containing the user’s ID and an expiration time.

  2. Set HttpOnly Cookies: Store the JWT in an HttpOnly cookie to ensure it’s inaccessible from client-side JavaScript, enhancing security.

  3. Automate Cookie Sending: The browser automatically includes cookies with each request, so no manual handling is needed on the frontend.

  4. Authenticate Requests: On each server request, check for the JWT cookie. If valid, authenticate the user; otherwise, redirect to login.

  5. Logout Handling: When logging out, remove ‘Remember Me’ cookies to prevent auto-login.

  6. Secure Token Management: Use HTTPS and a secure secret key to generate and validate JWTs. Ensure tokens expire after a set period for added security.

By following these steps, you can implement a secure and convenient automatic login feature on the frontend.
