thumb|upright=1.2|Passphrase generator in Bitwarden A passphrase is a sequence of words or other text used to control access to a computer system, program or data. It is similar to a password in usage, but a passphrase is generally longer for added security. Passphrases are often used to control both access to, and the operation of, cryptographic programs and systems, especially those that derive an encryption key from a passphrase. The origin of the term is by analogy with password. The modern concept of passphrases is believed to have been invented by Sigmund N. Porter in 1982.

密碼片語,又稱助記詞(英語:passphrase)是幾個英文單字或是資料的組合,用在電腦系統、軟體或是資料的存取控制上。密碼片語在使用上的用法類似認證用的密碼(英語:password),但為了安全性的考量,密碼片語的長度會比較長。密碼片語常用來存取加解密相關的軟體以及系統,也用在相關的機能中,特別是由密碼片語中衍生出加密密鑰的機能。密碼片語英文passphrase的起源是模仿password。一般認為現代密碼片語的概念是由Sigmund N. Porter在1982年所提出。
