Does Two Passwords Count as Two-Factor Authentication?

Multiple credentials are not necessarily multiple factors. The factors must come from different categories.

Something you know

Examples include passwords, PINs, and security answers.

Something you have

Examples include hardware tokens, authenticator devices, and smart cards.

Something you are

Examples include fingerprints, facial recognition, and other biometrics.

MFA

MFA combines two or more distinct factor categories. Password plus PIN is still knowledge plus knowledge.

The takeaway

Two passwords are two credentials, not two factors.
