Final answer:
The password 'Thomas12211995' is weak because it contains easily guessable elements such as a proper name and a significant date. Moreover, it lacks special characters, which are necessary for creating complex and secure passwords.
Step-by-step explanation:
The password in question, Thomas12211995, does have some weaknesses that could make it less secure. First and foremost, using a proper name like 'Thomas' and what appears to be a significant date, potentially a birthday, could make the password easier to guess by someone who knows the individual or can access their personal information. Moreover, although the password is long and includes both upper- and lowercase letters and numbers, it lacks special characters, which are essential for increasing the complexity of the password. Having a mixture of letters, numbers, and special characters makes a password much harder to crack. Therefore, one of the issues with the password is that it should include special characters to enhance its security.
