Cybersecurity is crucial for everyone, and two-factor authentication (2FA) is one of the simplest ways to secure your online accounts. 2FA adds an extra layer of security by requiring not just a password but also a second verification step, such as a code sent to your phone or an authentication app. Best of all, there are excellent free tools available for this purpose! In this guide, we’ll highlight some of the top free 2FA tools and provide a step-by-step guide for non-technical users to set them up.
What Is Two-Factor Authentication?
Two-factor authentication requires two methods to verify your identity:
- Something you know (e.g., your password).
- Something you have (e.g., a mobile device or an authentication app).
This additional layer makes it much harder for cybercriminals to gain access to your accounts, even if your password is compromised.
