The Secure Arc Mnemonic Password Generator is a very basic little utility application for the iPhone and iPod Touch that can generate complex passwords based on easy to remember phrases. Rather than having to either come up with simple and easy to remember passwords that can be guessed easily, or complex passwords that need to be written down or stored to be discovered by others, you just need to remember a sentence and have your iPhone or iPod Touch handy. The Mnemonic app is loosely based on 133t speak to map words in your sentence to characters in the generated password.
