Why is p@s5uu3Rd a better password than 53psuurd?

A password that combines various character types—such as uppercase letters, lowercase letters, numbers, and symbols—forms a more complex security structure. Therefore, the presence of an uppercase letter in p@s5uu3Rd increases its strength by adding complexity, making it harder to guess compared to a password that does not include uppercase letters.

Comparatively, the other choices do not contribute positively to password security. The second option, which suggests that the password uses only numbers, would actually weaken a password's strength since numerical-only passwords are easier to crack. Being shorter, as mentioned in the third option, often reduces a password's effectiveness, as it limits the possible combinations that can be used to crack it. Lastly, a password without symbols, as indicated in the fourth option, would typically be less secure, as the absence of symbols offers fewer variations to create a higher number of combinations.

In summary, the inclusion of an uppercase letter in p@s5uu3Rd enhances its overall security profile, making it a better choice for a password.
