Frequently Asked Questions
What is the most important aspect of password security?
The most important aspect is using unique, complex passwords for each account, combined with two-factor authentication. This significantly reduces the risk of multiple accounts being compromised if one password is stolen.
How can I tell if an email is a phishing attempt?
Look for suspicious sender addresses, generic greetings, urgent requests, poor grammar, and links that don't match the stated destination. Always verify the sender independently before clicking any links or providing information.
