Why Some Websites Prohibit the Use of Dictionary Words in Passwords

Many websites restrict the use of dictionary words in password creation for several reasons, with the primary focus being on enhancing security and preventing unauthorized access to user accounts. This article explores the rationale behind this practice and provides insights into how users can improve their password security.

Security Vulnerabilities

The primary reason for disallowing dictionary words in passwords is the increased risk of security vulnerabilities. Dictionary words are particularly susceptible to dictionary attacks, where attackers utilize precompiled lists of common words and phrases to guess passwords. These attacks are highly effective and can crack simple or predictable passwords quickly. By avoiding dictionary words, websites can significantly reduce the likelihood of such attacks succeeding.

Strength Requirements

Many websites encourage or require the use of complex passwords that include a mix of uppercase and lowercase letters, numbers, and special characters. This complexity makes it much harder for both human guessers and automated tools to crack these passwords. The requirement for complex passwords is a standard security practice that ensures a higher level of account protection.

Common Password Risks

Users often choose simple, easily remembered words or phrases, leading to weak passwords. Common examples include pet names, kids' names, birthdays, super heroes, cartoon characters, dog breeds, and fruit names. Such passwords are not secure against modern hacking techniques. Websites that enforce restrictions on dictionary words aim to prevent users from picking overly simplistic or common passwords, thereby enhancing overall security.

Compliance with Security Standards

Many organizations follow guidelines and best practices for password security, such as those set forth by the National Institute of Standards and Technology (NIST). These guidelines often recommend avoiding dictionary words to ensure better overall security. Compliance with these standards is crucial for maintaining the security of user data and complying with regulatory requirements.

Enhancing Security with Alternatives

Using a dictionary word defeats the purpose of using a password. Hackers can now guess word-based passwords in a matter of seconds to minutes. To enhance security, it is essential to use strong, unique passwords. This can be achieved by utilizing password managers, which generate and store complex passwords. One such password manager, LastPass, has been widely recommended and used for many years.

In my experience, LastPass is an exceptional tool for managing passwords securely. It installs freely on most devices and provides a password generator that can create up to 128 characters in length. This makes it an excellent choice for securing all critical documents, accessing email accounts, and storing sensitive information.

Conclusion

By implementing restrictions on the use of dictionary words in passwords, websites aim to protect user accounts from unauthorized access and improve overall security. It is crucial for users to understand these security measures and take advantage of tools like password managers to enhance their password security.

Donna, I respect sites that value the security of their site and its members. I recommend you avoid common dictionary words like pet names, kids' names, birthdays, and other easily guessable phrases. Use a password manager like LastPass to generate strong, unique passwords for all your accounts. You have no excuse for not securing all of your accounts with their own unique password. With the right tools, you can stay secure and protected online.
