See wikipedia:
> Multi-factor authentication (MFA) is a method of computer access control in which a user is only granted access after successfully presenting several separate pieces of evidence to an authentication mechanism - typically at least two of the following categories: knowledge (something they know); possession (something they have), and inherence (something they are).
So as long as your phone is sufficiently password-protected, that is is still 2fa.
- tombrossman 10y agoSo a laptop or phone with a fingerprint reader and TOTP app would qualify as well I suppose. I think many people assume that two separate devices are necessary for proper security, and I wonder if this is true?
- vel0city 10y agoYes, it would qualify. While having additional devices does increase security (harder to break into both the laptop and a phone, or laptop and smartcard/yubikey/RSA SecurID token) its not entirely necessary. Many physical security systems utilize multiple factors of authentication for access that are tied into a single reader. They often have a badge reader (something you have) and a fingerprint/eye scanner (something you are) or a PIN pad/digital combo dial (something you know) all built into the same device stuck on the wall. Sometimes they'll use separate systems for this, but the combo units are very common.
