NitroKey MFA (Multi Factor Authentication) keys can help stop phishing attacks, password breaches and secure your account much better than just a username and password alone. MFA requires you to have something you know (i.e., your password) and a device in your grasp (typically a device with either text-message (SMS) capabilities or a code generator app). In this case a NitroKey.
