Secure Passwords: How to Create Them to Defend Yourself from Hackers

In today’s digital world, passwords are the first line of defense against cyber attacks. Creating and maintaining a secure password is essential to protecting your privacy and personal data.

 

Why are they important?

Passwords play a crucial role in online security, as they act as access keys to our accounts. Using weak or predictable passwords can make our data vulnerable to breaches and hacker attacks. There are many threats, from phishing attempts to automated software that attempts to guess passwords. Having a secure password reduces the risk of falling victim to these attacks.

 

Characteristics of a Secure Password

Creating an effective password requires attention to various factors that increase its strength. Here are the main characteristics to consider.

Length and Complexity

A secure password must be sufficiently long. Generally, it is advisable that it be at least 12-16 characters long. Length adds an extra layer of security, making it harder for a hacker to guess or brute force the password with automated methods.

Use of Special Characters and Numbers

Passwords that combine uppercase and lowercase letters, numbers, and special symbols (#, &, %, etc.) are more difficult to crack. This variety increases the number of possible combinations exponentially, making it harder for someone trying to crack them.

Avoid Common Words and Simple Combinations

Commonly used words or predictable combinations like “123456” or “password” should be avoided at all costs. Hackers use lists of common passwords and easily guessable words in their attacks. It is preferable to create seemingly random combinations of letters and numbers.

 

Tools for Creating and Managing Strong Passwords

Managing many complex passwords can be difficult, but there are tools to help. Password managers allow you to generate, save, and manage complex passwords securely, reducing the risk of using weak or repeated passwords across multiple accounts. These tools encrypt passwords, making them accessible only with a strong master password.

 

Best Practices for Keeping Passwords Safe

It’s not enough to create a strong password; you also need to manage and maintain it properly. Here are some essential practices.

 

Regular Password Updates

Changing your passwords periodically is a good practice, especially for more sensitive accounts. Even if a password doesn’t appear to be compromised, regular updates can reduce the risk of unauthorized access in the future.

 

Two-Factor Authentication

Implementing two-factor authentication (2FA) is one of the most effective ways to protect your accounts. This adds an extra layer of security by requiring a second verification step, such as a code sent via SMS or generated by a dedicated app.

 

What to do if a password is compromised

If you suspect that one of your passwords has been compromised, act immediately. Change the compromised password on all accounts where it was used, enable two-factor authentication, and monitor your accounts for suspicious activity if necessary. Using a password manager will help you track changes and create new, secure passwords.
