Abstract

Passphrases are considered to be more secure than passwords since they are longer than passwords. However, users choose predictable word patterns and common phrases to make passphrases memorable, which in turn significantly lowers security. While random passphrases appear to be stronger, surprisingly they are neither strong nor memorable. In this paper, we present the latest passphrase research, and introduce a new way to create a passphrase using mnemonics. Passphrase generation using mnemonics shows promising results in improving both strength and memorability.
