3. Make your password at least 8-12 characters long.

Remember to create a unique password for each account and avoid using the same one across multiple platforms. If one of your accounts is compromised, the rest will remain secure. Consider using a password manager to store and generate strong passwords for all your accounts securely.

Encryption and data protection

While a strong password provides a good level of security, adding an extra layer of protection through two-factor authentication (2FA) further enhances your computer security. 2FA requires you to provide two forms of identification before accessing your accounts. This typically involves entering your password and confirming your identity through a second method, such as a fingerprint scan, a text message verification code, or a security question.

By enabling 2FA, even if someone can obtain your password, they won’t be able to access your accounts without the second authentication factor. This dramatically reduces the risk of unauthorized access to your sensitive information, as it would require the hacker to have physical possession of your second factor or knowledge of your security question.

Regular software updates and patches

In addition to using strong passwords and enabling two-factor authentication, encryption is vital in securing your data. Encryption converts your data into a format that can only be read or accessed with a decryption key. This ensures that even if your data is intercepted, it remains unreadable and useless to unauthorized individuals.

Various encryption methods, including end-to-end encryption, ensure that only the sender and intended recipient can access the data. This is commonly used in messaging apps to protect the privacy of conversations. Additionally, encrypting your hard drive or specific files and folders provides an added layer of protection against unauthorized access in case your device is lost or stolen.

Regularly backing up your data is another essential aspect of data protection.
