Understanding Multifactor Authentication

What Multifactor Authentication really means

MFA adds another verification step beyond only a password. That second factor can be something like an authenticator app approval, a code, a hardware key, or another trusted factor. :contentReference[oaicite:13]{index=13}

A user enters the first factor, often a password, and then must complete an additional verification step before access is granted. This makes account compromise harder if a password is stolen. :contentReference[oaicite:14]{index=14}

MFA matters because password theft remains one of the most common ways attackers get into accounts. Microsoft specifically notes that MFA makes it much harder for attackers to succeed with stolen passwords. :contentReference[oaicite:15]{index=15}

A common misconception is that MFA means typing a code every time in every system. In practice, the experience depends on the setup and can include app prompts or other methods. :contentReference[oaicite:16]{index=16}
