How is key stretching effective in resisting password attacks?

How is key stretching effective in resisting password attacks? It takes more time to generate candidate password digests. It requires the use of GPUs. It does not require the use of salts.

Are Diceware passwords secure?

Security is achieved by random word selection. … The maximum length of Diceware words is 5 characters. That makes a Diceware passphrase easier to enter accurately, particularly on mobile devices. Also many password protected systems limit the length of allowable passphrases.

What is the strongest type of password?

1. Mix meanless Word, number and symbol randomly, and at least 15 length. Mix meanless Word, number and symbol randomly, and at least 15 length (mix uppercase and lowercase). Actually, strongest password equals to hardest remember password, for example “E7r9t8@Q#h%Hy+M”.

Why are long passwords stronger than short passwords?
