What is a Passphrase?
A passphrase is a long password made from multiple random words. Long passphrases are often easier to remember while still providing excellent security.
Unlike short passwords, passphrases rely heavily on length and randomness, making them highly resistant to brute-force attacks.
How Secure Are Passphrases?
Passphrases become significantly more secure as additional random words are added. A six-word random passphrase can provide excellent protection against brute-force attacks.
Using randomly selected words is much safer than using quotes, song lyrics, or predictable word combinations.
Why Use Passphrases?
- Harder to brute-force due to length
- Easier to remember than random symbols
- Excellent for password managers and encryption
- Strong protection against credential stuffing attacks
- Ideal for securing important online accounts
Best Practices for Secure Passphrases
Use unique passphrases for important accounts and avoid reusing passphrases across websites. Password managers can help securely store long passphrases.
Enabling two-factor authentication (2FA) adds an additional layer of protection even if a password or passphrase becomes compromised.
What is Diceware?
Diceware is a method for creating secure passphrases using randomly selected words from a predefined wordlist. The approach was designed to maximize randomness while keeping passphrases memorable.
