A credential that uses public-key cryptography to authenticate a human user to a system or online service. A passkey typically consists of a private key stored on, or accessible through, a computer, mobile device or security key, with a corresponding public key held by the system or online service being authenticated to. Passkey authentication may provide single-factor or multi-factor authentication. It provides multi-factor authentication where use of the private key requires a separate activation factor, such as a password or biometric.
A sequence of words or text used to control access to a computer system, program or data. A passphrase is similar to a password in usage, but is generally longer for added security.
A sequence of characters used for authentication. Passwords consisting solely of numbers are also known as personal identification numbers, while passwords consisting solely of a sequence of words are also known as passphrases.
