What is 2-Factor authentication?
Two factor authentication is term used to describe any authentication mechanism where more than one thing is required to authentate a user.The two components of two factor authentication are:
- Something you know
- Something you have
Traditional authentication schemes used username and password pairs to authenticate users. This provides minimal security, because many user passwords are very easy to guess.
In the most common implementations of two factor authentication, the something you have component is provided by a small token such as RSA token.
With RCDevs authentication solutions, the token is replaced by the mobile phone.
