Enhancing email security through multi-factor authentication

Many users overlook one critical security setting that can stop hackers in their tracks: multi-factor authentication (MFA). Passwords alone are no longer enough. Easy-to-remember passwords are insecure, and strong passwords are rarely memorable or widely reused.

Brute-force attacks and credential leaks are common, especially since many users repeat passwords across different platforms. MFA solves this by requiring a second verification form, usually from your phone or an authenticator app, to confirm your identity.

The extra step can block attackers, even if they have your password, because they still need access to your second device. Two-factor authentication (2FA) is the most common form of MFA. It combines something you know (your password) with something you have.

Many email providers, including Gmail, Outlook, and Proton Mail, now offer built-in 2FA options under account security settings. On Gmail, visit your Google Account, select Security, and enable 2-Step Verification. Use Google Authenticator instead of SMS for better safety.

Outlook.com users can turn on 2FA through their Microsoft account’s Security settings, using an authenticator app for code generation. Proton Mail allows you to scan a QR code with Google Authenticator after enabling 2FA under Account and Password settings.

Authenticator apps are preferred over SMS, as they are vulnerable to SIM-swapping and phishing-based interception. Adding MFA is a fast, simple way to strengthen your email security and avoid becoming a victim of password-related breaches.
