- Use environment variables, never hardcode credentials
- App Passwords are 16 characters (format: xxxx xxxx xxxx xxxx)
- Revoke app passwords if compromised

## Troubleshooting

- Verify App Password is correct (16 chars, no spaces)
- Make sure 2FA is enabled on your Google account

**"Could not connect"**
- Check firewall/network settings
- Gmail may block connections from unknown apps
