What Is Special Character In Password

How To Articles

I would like to emphasize that in today’s digital era, password security is incredibly important. In order to access our various online accounts, we are required to create passwords and it is essential to ensure that those passwords are strong and secure. A crucial component of a strong password is the inclusion of special characters.

Special characters refer to non-alphanumeric characters such as !, @, #, $, %, etc. These characters add an extra layer of complexity to your password, making it harder for hackers and brute-force attacks to crack. Including special characters in your password significantly increases its strength and reduces the risk of unauthorized access to your accounts.

Now, let’s dive deeper into the role of special characters in password security. When we create a password, we often tend to use simple and easily guessable words or phrases. This makes our passwords vulnerable to dictionary attacks, where hackers use automated programs to try every word in the dictionary until they find a match. Including special characters in your password can help protect against such attacks.

Special characters provide a wider range of characters for password combinations, making it more difficult for attackers to crack your password. For example, if your password includes only lowercase letters and numbers, there are 36 possible combinations for each character. However, if you add special characters to the mix, the number of possible combinations increases significantly.

Another reason why special characters are important is that they can help prevent rainbow table attacks. A rainbow table is a precomputed table of hash values for commonly used passwords. By adding special characters to your password, you make it less likely to be found in a rainbow table, thus adding an extra layer of security.

However, it’s important to note that not all websites or applications allow special characters in passwords. Some platforms have restrictions on the types of characters that can be used, which can be frustrating at times. In such cases, it’s best to follow the specific requirements of each platform while still creating a strong and unique password.

In conclusion, including special characters in your passwords is highly recommended for enhancing security. By adding these non-alphanumeric characters, you make your password more complex and resistant to various hacking techniques. Remember to mix and match different types of characters, use a combination of uppercase and lowercase letters, numbers, and special characters for optimal password strength. Stay safe online!


Special characters play a crucial role in password security, adding an extra layer of protection to your online accounts. By including these non-alphanumeric characters, you enhance the complexity of your passwords and reduce the risk of unauthorized access. However, it’s important to keep in mind that not all platforms allow special characters, so make sure to follow the specific requirements of each website or application while still creating a strong and unique password. Stay vigilant and prioritize your online security!
