Two-factor authentication (2FA)

A method of accessing an account or a service when a user is required to provide extra data apart from the usual log in and password. It can be in the form of secret questions, access codes, etc. It is used for extra data protection, but has inconvenient consequences if you use any external service that requires the data.
