A passphrase is a sequence of words or other text used to control access to a computer system, program, or data. Unlike a password, which is typically a random sequence of characters, a passphrase is often a sequence of words or a sentence, making it generally longer and more secure.
Passphrases bring several advantages over traditional passwords:
Short and uncomplicated passwords are susceptible to both manual and automated attacks. Automated tools can attempt thousands or even millions of guesses in a short amount of time, quickly cracking simple passwords. A longer passphrase, especially one with a mix of word capitalization or added numbers, dramatically increases the potential combinations, making automated attacks far less feasible.
When creating a passphrase, consider the following tips:
Note: Always ensure that you store and manage your passphrases securely. Consider using a passphrase manager if you have multiple to keep track of.
