It acts as a barrier between your device and external threats, ensuring that only authorized connections can be established.
Using multi-factor authentication (MFA) is a vital security measure that helps protect your online accounts. MFA requires multiple methods to verify your identity before granting access to your accounts. These could be a combination of something you know (such as a password), something you have (like a physical token), and something you are (biometrics, for instance). By implementing MFA, even if your password gets compromised, hackers will have a harder time accessing your account because they lack the other authentication factors.
Finally, password managers are a convenient tool that can significantly improve your online security. Password managers store and generate complex, unique passwords for your various accounts, helping to reduce the risk of password-related breaches. By entrusting your passwords to a secure manager, you can eliminate the need for easily guessable passwords or keeping track of multiple complex passwords.
Incorporating these additional online security measures will help ensure your digital safety, even when not connected to Wi-Fi or using a VPN. Remember to regularly update your software and stay informed about the ever-evolving world of cybersecurity.
Securing Your Browsing Data
