Use Two-Factor Authentication (2FA)

February 2026 — Tip of the Month

"Would you like to set up two-factor authentication for this account?"

I recommend selecting Yes.

Two-factor authentication (commonly "2FA") is a security measure that requires two different forms of identification to access an online account. This extra layer of protection significantly reduces the risk of unauthorized access, making it far more difficult for hackers to compromise your accounts, even if they manage to obtain your password. Data breaches and phishing attacks are increasingly common, and 2FA is one of the most effective tools available for safeguarding your online presence.

2FA is particularly important for sensitive accounts, such as your primary email account. Your email address often serves as the gateway to your digital life. Notably, it's where password reset links and crucial notifications are sent. If someone gains control of your email, they can potentially access your financial accounts, social media accounts, and other sensitive data. 2FA prevents this by requiring a second verification step, such as a code sent to your phone or generated by an authentication app, in addition to your password.

Implementing 2FA is straightforward and is now supported by most major online service providers. You can typically enable it in your account's security settings and choose your preferred authentication method — text message, authenticator app, or hardware key. Once activated, even if your password is stolen, a hacker would still need access to your second factor (like your mobile phone) to break into your account. This makes your sensitive information exponentially safer with minimal inconvenience.

▶ Some online accounts only require 2FA once per device (or browser). After verifying your identity with a second factor, the service "remembers" your device for a while (such 30 days or a year). This helps improve security while reducing hassle.

In summary, enabling 2FA on your most important accounts, especially your primary email, is a simple yet powerful way to protect your data and privacy. So next time your online account informs you 2FA is available and offers you the chance to add it, say yes. The short-term hassle far outweighs the hardships of getting hacked.
