You might not have any idea about this, but you already make use of 2-factor authentication in today’s present world. Once you get to know what it actually is, you will get easily get convinced about the fact that using this with “mission- critical online services” is a great idea.
Two- factor authentication or commonly known as 2FA as it adds a bit of extra security in your basic sign-in procedure.

2 Factor Authentications: In Brief:
2FA or 2 factor authentication is actually for adding a second layer of verification to your account sign-in. When you are only entering your password and username, you are making use of a single factor verification. But when you are using two-factor authentication, you will have to make use of two or even tree sorts of credentials before getting the permission of accessing an account.
There are basically three sorts of 2-factor authentication:
- Something that you already are, like a biometric, using voice prints or figure prints.
- Anything that you already have, like fob, phone or ATM card number.
- Something that you already know like any specific pattern, password, or identification number or PIN.
Use of this two step verification system doesn’t only provide a better security to your profile, but also safeguards you from the hackers, who constantly tries o invade your privacy. Though it doesn’t provide you with a specific guarantee of protecting you from hankers, but surely promises to try their level best such that they can meet all privacy that is required or demanded by your account.
