Research shows that 2FA adoption is most common among employed people, with 79% of those using 2FA according to a survey conducted by Duo Security. This trend has risen from 28% in 2017 to 79% in 2021. The most common method of authenticating is through SMS, but study shows that there are alternative options that are more effective.
From a 2019 Microsoft report, we see that 2FA has successfully blocked 99.9% of automated attacks. In light of this data, when done correctly, 2FA greatly reduces the chance of an attacker gaining your personal data. The more secure you are about what you know and who you are, the more difficult it will be for a hacker to break into your account.
Two-factor authentication guards against phishing, social engineering, and brute-force password attacks and safeguards login attempts against attackers with weak or stolen credentials. This significantly boosts the security of logins. more specifically, two-factor authentication prevents nearly all automated bot-related attacks. Certain risks still exist depending on which 2FA you authenticate with – it is advised to create a complex password for 2FA.
Even with more security each year, hackers can still bypass two-factor authentication with sophisticated phishing attacks. It’s critical that both individuals and businesses have extra layers of security such as multi-factor authentication.
Two-factor authentication (2FA) is one of the types of multi-factor authentication. There are as many factors of authentication as there are ways to confirm the user’s identity (location, fingerprints, face, security keys), and any security protocol that includes three or more factors is considered MFA. two-factor authentication is the most commonly used subset of multi-factor authentication and is readily available.
