Frequently asked questions
Are a password and a PIN two different factors?
Not by themselves. Both are knowledge factors. MFA requires different factor types, such as something you know and something you possess.
Does MFA prevent every account compromise?
No. Method strength, session security, recovery, and configuration still matter. Phishing-resistant methods reduce important attack paths.
