Answer :
We are advised to use letters, numbers, and special characters in passwords to enhance security and make them more difficult for unauthorized users to guess or crack. Here's why:
Complexity and Variability: Adding a mix of uppercase and lowercase letters, numbers, and special characters increases the complexity of the password. This means there are more possible combinations, making it exponentially harder for attackers to guess the password using brute force methods.
Protecting Personal Information: A strong password helps protect your personal information, such as emails, bank accounts, and social media profiles from being accessed by hackers.
Resisting Common Attacks: One common method attackers use is the "dictionary attack," where they try common words and phrases from the dictionary. Including numbers and special characters makes your password less likely to be found in such attacks.
Preventing Unauthorized Access: Stronger passwords make it more difficult for someone trying to gain unauthorized access to your accounts, especially if they are using automated tools to attempt many passwords quickly.
Security Standards: Many systems and websites require a combination of letters, numbers, and special characters to meet security standards and policies. These standards are in place to help protect users.
Overall, using a mixture of letters, numbers, and special characters is a simple yet highly effective way to improve the security of your passwords.
