What security implications should I consider when troubleshooting the HP printer scan-to-email certificate error?

When troubleshooting, be mindful of security risks. Disabling firewalls or enabling 'less secure apps' on your email account could expose your account to potential threats. Always re-enable firewalls and, after testing, disable 'less secure apps' if you are not using app-specific passwords. Ensure your printer is on a secure network and consider using strong passwords and enabling two-factor authentication for your email account.
