Multi-factor authentication (MFA) strengthens account security by requiring two factors to verify your identity. These factors usually include something you know (like a username and password) plus something you own (like a smartphone).
MFA protects against phishing, social engineering, and password brute-force attacks and secures your logins from attackers exploiting weak or stolen credentials. With MFA, your password alone is no longer enough to access your account, dramatically improving account security.
