❓ Frequently Asked Questions
What makes a password strong?
A strong password is long (ideally 12-16+ characters), uses a mix of uppercase, lowercase, numbers, and symbols, and avoids common words or patterns. A passphrase can be effective if it is long and unique.
Why should you use unique passwords for each account?
If one site is breached and your password is leaked, unique passwords prevent attackers from accessing your other accounts.
What is a password manager and how can it help?
A password manager securely stores and autofills your passwords, generates strong ones, and helps you avoid reusing passwords. Use a strong master password to protect it.
What is multi-factor authentication (MFA) and why is it important?
MFA requires an additional verification factor (like a code from an authenticator app, SMS, or a hardware key) beyond your password, providing extra protection even if the password is stolen.
When should you update or change your passwords?
Change passwords after a known breach or if you suspect a password has been compromised. Otherwise, focus on using unique, strong passwords and enabling MFA.
