Multi-Factor Authentication Two-Factor Authentication (2FA)

Today I am going to be writing about Two-Factor Authentication. It is also known as 2FA. At first, we need to know about 2FA (Two-Factor Authentication). It is an extra security layer that is known as Multi-Factor Authentication.

As we know about the standard procedure of the security we need only a username and password that process called SFA (Single Factor Authentication). Today this standard security procedure is not safe because hackers can easily get username or password of any account and access easily. Cyber-crime increases day by day in today’s world because of the use of digital accounts increases day by day.

Two-step Verification is also known as multi-factor authentication. Initially, two-factor authentication is announced by Goggle in 2011 for their user’s protection. It is not a new thought but its use uses more important with the digital age. After that MSN and Yahoo also use 2FA secure layer for their users.

2FA is more secure because in 2FA we need username, password and authentication information or physical token that the user receives immediately. This token is received by Voice Call or OTP (One Time Password). Token may be in numeric and alphabetic form.

Physical Authentication Keys is also using in Dual Factor Authentication (2FA) security. This is also called U2F (Universal 2nd Factor) and it was created by Yubico and Google with contribution from NXP. U2F is an encrypted USB key that is using to login account as security.
