In today’s digital landscape, securing your online accounts is more important than ever. With cyber threats on the rise, relying solely on passwords is no longer sufficient. Two-factor authentication (2FA) provides an additional layer of security by requiring two forms of verification before granting access to your account. This article explores the benefits of 2FA and highlights some of the best free tools available to help you secure your online accounts in Sri Lanka.
What is Two-Factor Authentication (2FA)?
Two-factor authentication is a security process that requires two different forms of identification before accessing an account. Typically, this involves something you know (like a password) and something you have (like a mobile device). This extra layer of security helps protect against unauthorized access, even if someone manages to steal your password.
Why Use 2FA?
- Enhanced Security: 2FA significantly reduces the risk of unauthorized access to your accounts. Even if your password is compromised, the attacker would still need the second factor to gain entry.
- Peace of Mind: Knowing that your accounts are secured with an additional layer of protection allows you to browse and conduct online transactions with confidence.
- Compliance: Many businesses in Sri Lanka are now required to adhere to data protection regulations, making 2FA a necessary compliance measure.
