Which of these is considered a strong password?

A strong password is one that is complex and difficult for someone to guess or crack. It typically includes a mix of upper and lower case letters, numbers, and special characters, making it harder for unauthorized individuals to gain access.

The choice that exemplifies a strong password is "Garfield>The>Naughty>Cat." This password is strong because it is lengthy, includes uppercase and lowercase letters, and incorporates special characters (the greater-than signs), as well as being more complex than simply using common words or simple patterns. Length and complexity significantly enhance the security of a password, making it less susceptible to attacks such as brute force or dictionary attacks.

In contrast, the other options are weak. "12345678" and "abcd1234" are straightforward and utilize basic number and letter sequences that are easily guessable. "Password" is one of the most commonly used passwords and is well-known for being insecure. A strong password should always defy easy recognition or predictability, which is why the choice that includes a creative and varied structure is the best option.
