2FA

Definition:

Short for 2-factor authentication. This is an extra security step, in addition to username and password, used to log in to (web2) websites and services. It is usually in the form of a code that is generated by an app on the user’s (mobile) device or a code generated online and sent to the user’s email address or phone. Codes sent to phones by SMS are vulnerable to attack in the event that someone clones the sim card or phone number, while codes generated by a user’s mobile authenticator app or dedicated hardware device are considered safer.
