Which aspect makes 'p@s5uu3Rd' a stronger password compared to '53psuurd'?

The strength of the password 'p@s5uu3Rd' primarily comes from its inclusion of uppercase letters, symbols, and its longer length. Passwords that contain a combination of different character types—such as uppercase letters, lowercase letters, numbers, and symbols—are generally harder to crack compared to those that use only one type of character. This increased complexity results in a larger number of potential combinations, making brute-force attacks against the password significantly more difficult.

Additionally, the length of the password contributes to its strength; longer passwords have exponentially more possible combinations than shorter ones, further enhancing security. In contrast, '53psuurd' lacks uppercase letters and symbols, making it easier for attackers to predict or guess. Therefore, the combination of various character types and increased length in 'p@s5uu3Rd' creates a markedly stronger password compared to '53psuurd'.
