Have you ever forgotten your password online and you were asked a recovery question or a code was sent to the phone or email you used to register for that particular site/app?
That is a typical example of 2-Factor Authentication.
Two-factor authentication (also known as 2FA) is a type of multi-factor authentication. It is a way of confirming user identity by using a combination of two different factors: 1) something they know, 2) something they have, or 3) something they are.
Another good example of two-factor authentication is the withdrawing of money from an ATM; only the correct combination of a bank card(something the user possesses) and a PIN (something the user knows) allows the transaction to be carried out.
Two other examples are to supplement a user-controlled password with a one-time password (OTP) or code generated or received by an authenticator (e.g. a security token or smartphone) that only the user possesses.
There are many reasons why you should always opt for 2FA, some are listed below:
65% of people use the same password on all their login accounts which is like having just one key opening everywhere in your house.
90% of all staff passwords are hackable in just under 6-hours.
The most common password in the world is the word “password”.
With these, it is not difficult to see why 90% of staff passwords are considered “hackable”. 2FA is a means to keep your accounts safe from cyberhacks.
