Two-factor authentication (2fa), or a code sent to your phone to verify your identity and helps prevent cyber criminals from accessing your private information such as a fingerprint scan, an extra step is added to the login process. 2fa offers an extra level of security that cybercriminals can't easily access because the criminal needs more than just your username and password credentials.


2FA is a subset of multifactor authentication, which is an electronic authentication method that requires the user to prove their identity in multiple ways before they are allowed to access an account. Two-factor authentication is named because it requires a combination of two factors, while multi-factor authentication may require more.


A good example of two-factor authentication in the real world is an ATM card. In addition to presenting the card physically, you also need to enter your PIN to access your account.



On the web, you can find examples of 2fa just by browsing through your browser history. You will find many websites where all you need is your username or email and password. They use single-factor authentication, where the password is all you need for login.


As the name implies, two-factor authentication requires an extra step and a second factor to log in to a site or access an online account. Most often, first enter your username and password. The site usually sends a text message with a six-digit numeric code to your mobile phone. This code is called an authenticator, or sometimes a password or verification code. You can access the site only by entering this code, which appears on your mobile device. If you don't have a code, you can't log in even if you know the correct password.

2FA why should I use it?

Passwords are historically weak, both due to the advanced nature of hacking and a general annoyance with password creation and use. A Harris poll found that 78% of Gen Zs use the same password on multiple accounts, increasing the Overall vulnerability if an offender finds their credentials. And beyond that: about 23 million accounts still use the password "123456".”


As it becomes easier and easier for cybercriminals to guess passwords, 2fa is becoming more important than ever. It may seem difficult to add an extra step to your Internet browsing, but without it you may be leaving yourself vulnerable to cybercriminals who want to steal your personal information, access your bank accounts, or break into your online credit card portals.


Adding an extra step to account access means that thieves will struggle to access your personal information. If you add an information factor to your bank account, a cybercriminal who knows your password will not be able to access the account without october your phone when he receives the verification code.


In this way, those who still rely on the “password " password have a better chance of keeping their bank account safe.

HOW DOES 2FA WORK?

To understand two-factor authentication, you first need to understand the factors. The A2fa factor is what you will need to access the account, and they are usually divided into three categories:

Information: These factors require you to know something such as security questions, a PIN sent to your device, or a specific keystroke.

Ownership: the user must physically own the factor, such as a bank card or USB drive, and plug it into the device to log in.

Biology: access is granted when the user proves his/her identity through biological markers such as fingerprints or voice.
