A password is a sequence of characters, typically shorter in length, that is used to authenticate a user and grant access to a system or account. A passphrase, on the other hand, is a longer sequence of words or phrases that is used in a similar way to a password.
The main difference between a password and a passphrase is their length and complexity. Passwords are generally shorter and often contain a mix of letters, numbers, and symbols to make them harder to guess. Passphrases, on the other hand, are longer and may consist of multiple words or phrases strung together, making them easier to remember and type accurately.
While both passwords and passphrases can be used to protect user accounts and systems, passphrases are generally considered more secure because they are longer and easier to remember, making them less likely to be written down or shared.
