You hear about hacks all the time. The news covers major websites who have had data leaks containing your email and password. Computers get infected and capture your login details for bank accounts and credit cards. In the worst cases, identity theft occurs because it is an easy crime to commit with a high reward.
To combat the criminal element the technology industry has developed 2FA. Sometimes referred to as multiple-step or multi-factor verification.
2FA is a way to double check a person’s identity by getting a person to product two separate forms of identification to gain access to a computer or a website.
2FA methods rely on a user providing a password, as well as a second factor, usually either a security token (a text to a phone or a code from a 2FA application) or a biometric factor, such as a fingerprint or facial scan.
Hence 2FA adds an additional layer of security to the authentication process by making it harder for attackers to gain access to a person’s devices or online accounts because knowing the victim’s password alone is not enough to pass the authentication check.
If you get a notification that you have not requested then you know that someone else is trying to access your account.
Remember to have a different password for every account, if someone can guess one of your password using software programs, they could have access to all your bank, email and social media accounts!
If your bank, a website or email provider (eg hotmail.com or gmail.com) offers you the opportunity to set up 2FA then I would definitely recommend it.
