Second Factor
User authentication is in a period of transition and that has necessitated second factor security. One thing almost everyone seems to agree on is that passwords have become a security liability, and though many major organizations and companies like Microsoft and Apple have placed their chips on biometrics, others have taken the two-factor route. 
Two-factor authentication doesn’t do away with the password, it bolsters it. A two step login usually requires a password and a device factor, but it can also take the form of QR codes, location factors and one time password tokens. A security paradigm supported by the FIDO Alliance’s U2F specifications, two-factor authentication is readily available for use across a wide range of applications.
