Final answer:

A passphrase makes use of two totally unrelated words to enhance security while being easier to remember.

Explanation:

A passphrase makes use of two totally unrelated words. Instead of a complex combination of random characters, a passphrase consists of words that are easier to remember yet provide strong security.

For example, a passphrase like 'sunflower pencil' is more secure than a simple word or phrase and easier to remember than a string of random characters.
