Two-factor authentication (2FA) is an important security feature that can help protect your digital accounts from malicious actors. It requires users to prove their identity with two independent pieces of evidence: something you know, like a password, and something you have, like a physical token or a smartphone. Turning on 2FA for your online accounts makes it more difficult for hackers to gain access to your sensitive data.
2FA can be inconvenient, but I think the small distraction far outweighs the risk. Nearly every breach case I investigated could have been delayed or averted by implementing 2FA. Tech companies are researching even more secure methods than 2FA but for now, do yourself a favor and turn it on for every single website that allows you the option to do so.
