What is Passphrase?

A passphrase is a specialized type of password which is structured as a specifically ordered sequence of words, which is used to access a particular account, device, or system. Since passphrases are typically composed of individual coherent words rather than an abstract string of letters, numbers, and symbols, they are often easier to remember than random passwords, although passphrases offer a similar — and at times even higher — level of security when properly applied. Within the blockchain industry, passphrases are commonly used as a security mechanism which helps users protect their cryptocurrency assets by mitigating the risk of an account hack and/or unauthorized third-party access.
