Hi

To verify the registered email of users before signing in, you'll first need to set up email functionality in your Laravel application.

You can configure the email settings in your `.env` file to set up email verification. For testing, you can use a service like Mailtrap to simulate the email verification process.

In your Laravel project, open the .env file located in the root directory. Update the following variables with your email configuration:

MAIL_MAILER=smtp
MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=your_mailtrap_username
MAIL_PASSWORD=your_mailtrap_password
MAIL_ENCRYPTION=tls
