What is 2FA and how it helps the end users globally?
2FA, also referred to as Two Factor Authentication, is a security method that adds an extra layer or factor in the login procedure along with password to verify identity of the user. Two Factor Authentication security method authenticates the users by using two factors; something you know (your secret password) and something you have (your mobile phone to receive unique verification code) or something you are (biometric characteristics like iris, retina, face scan, voice recognition, fingerprint), in the login procedure to verify their identity.
Usually, the end users log in to their valuable online accounts using just password-only verification process. This process of logging the accounts is referred to as 1FA (One Factor Authentication), and it’s not highly secure. But, with 2FA security method, an end user requires to provide the secret password along with a unique verification code in the login procedure to verify his identity, and gain access to the account. This unique verification code is sent to the registered mobile device of the user at every login attempt, and is valid only for a few seconds.
If any unauthorized user steals your secret password, then also accessing the account will not be an easy task for him. It is because once he enters the valid password, a unique verification code or OTP (One Time Password) will be sent to your registered mobile device to complete the second step of verification, and gain access to the account.
In this way, 2FA (Two Factor Authentication) security method secures all your valuable online accounts from different types of harmful external threats by requiring both secret password and a unique verification code in the login procedure.
