How to Generate Google Email App Password

To send email alerts, you need to generate a Google Email App Password. Follow these steps:

1. Enable Two-Factor Authentication:

   • Go to your Google Account: https://myaccount.google.com/
   • Click on "Security" in the left-hand menu.
   • Under "Signing in to Google," click on "2-Step Verification" and follow the steps to set it up.

2. Generate App Password:

   • After enabling 2-Step Verification, return to the "Security" section.
   • Under "Signing in to Google," click on "App Passwords."
   • You might need to sign in again.
   • At the bottom of the screen, click on "Select app" and choose "Other (Custom name)".
   • Enter a custom name (e.g., "Web Monitor") and click "Generate."
   • Google will display a 16-character app password. Copy this password.

3. Update Email Settings in the Code:

   • In app.py, update the EMAIL_USER and EMAIL_PASSWORD variables with your email and the generated app password.

   EMAIL_USER = "your-email@gmail.com"
   EMAIL_PASSWORD = "your-app-password"  # Replace with the 16-character app password
