A passphrase is used to enhance security by providing a longer and more complex alternative to traditional passwords. Its purpose includes:
- Increased Security: Longer passphrases are generally harder to crack than shorter passwords.
- Memorability: A passphrase can be a sentence or a combination of words that is easier to remember than a random string of characters.
- Resistance to Attacks: Passphrases can help protect against brute-force attacks and dictionary attacks due to their complexity and length.
Overall, the main goal of a passphrase is to provide a stronger layer of security for accessing sensitive information or systems.
