Is combining nonsense words with number-letter substitutions a good strategy for creating passwords?

Combining nonsense words with number-letter substitutions creates a strong password strategy because it increases complexity and randomness. Nonsense words are terms that do not have any meaning; this reduces the risk of a potential attacker guessing the password based on known words or phrases. Furthermore, by incorporating number-letter substitutions—where, for example, an 'A' might be replaced with '4' or an 'O' with '0'—you add an additional layer of difficulty. This method makes it harder for automated systems or hackers to crack the password since they would need to account for both the nonsensical nature of the words and the various substitutions.

The strength of a password lies in its unpredictability and length. Using random, nonsensical combinations with substitutions ensures that passwords won't be integrated into dictionary attacks, which often target common words and phrases. Thus, a combination of nonsensical words and number-letter substitutions results in strong passwords that are resilient against common hacking techniques.
